4. Why? • Just like the LHC we are searching for new physics Adrian Bevan

5. Why? • Just like the LHC we are searching for new physics • Can also do precision SM tests (CKM + EW). • N.B. SuperB will be the only experiment to directly and indirectly probe the charm cu triangle, this is a unique test of CKM and is highly sensitive to NP. • A number of observables can only be measured at SuperB • Many observables will be more precise at SuperB than Belle II Adrian Bevan

6. Adrian Bevan

7. With the exceptions of yCP and K*μμ, there are no planned or existing experiments that will surpass SuperB precision in these modes for at least the next two decades. • The best place to measure the other 33 golden modes is SuperB! Adrian Bevan

8. Status Funding Site Choice Machine Detector Organisation UK Involvement Adrian Bevan

9. Funding • The project was funded by the Italian senateon 14/15th December 2010. • Identified funding for the project (need 500M€) • 250M€ new money from Italian government to set up the new facility. • 100M€ from the Italian institute of technology. • $200M in kind contribution from DOE. • Reciprocity agreement between Russia and Italy on Fusion/SuperB will bring additional funding. • The cost of the machine/facility is covered. • The detector cost is broken down as follows: • Re-use of parts from BaBar: 50% of the cost • INFN will contribute ~25M€ • Overseas partners need to contribute ~25M€ Adrian Bevan

10. Site Choice • The Nicola Cabibbo Laboratory, Tor Vergata (Rome). • Announced May 2011 at the SuperB Kick off meeting Adrian Bevan

12. c/o Sanelli/Tomassini, Elba Kick off meeting 2011 Archeological remains: no important remains are on the SuperB area according to a searching campaign done before the construction of the sport city. Creek: In the middle of the site there is a small torrent. It is almost dried out for long period of the year. Due to the fact that it is not part of a strategic area, there is the possibility to deviate the path connecting the highway guard creek. Adrian Bevan

13. Machine • Lattice parameters stable (this has been the case for some time) • Several routes to nominal luminosity. • ϒ(4S) lumi 1036 cm-2s-1 • ψ(3770) lumi 1035 cm-2s-1 • All parameters demonstrated individually at machines around the world .... SuperB will bring them together in one place. • KEK have now adopted the SuperB low-emittance machine design. Adrian Bevan

16. Organisation • We're now in a transition phase: • Collaboration forming has started • Project management boards are in the process of being set up for: global oversight, machine, detector. • Proto-tech board, Speaker's Bureau, Governance committee etc. are operating now. • These will transform into the governance and oversight structure of the collaboration over the coming months. Adrian Bevan

17. Organisation • The SuperB community includes: • Canada, France, Italy, Norway, Poland, Russia, Spain, UK, Ukraine, USA • Other countries are following the progress closely. • Start international organisation using a Limited Liability Company framework (like Diamond). • Quick to set up. • Need to be involved now if we want to have a input into decision making. • In the longer term the Project will come together as an ERIC: European Research Infrastructure Consortium. • Simplifies the legal framework for participating countries (use EU law, rather than regional specialities). • Tax exempt status. • Similar to the way CERN operates. • UK has signed a non-disclosure agreement with INFN to collaborate on INMAPS CMOS sensor development. • The UK is already benefiting financially from our involvement in SuperB. Adrian Bevan

18. UK Involvement • Very successful workshop at Oxford: • http://www.physics.ox.ac.uk/superB/index.asp • ASTEC, Cockcroft, Diamond, JAI, QMUL, RAL want to work on SuperB • Strong accelerator and detector teams have significant interest, but long term involvement will need financial support. • RAL and QMUL have established interests in the project. • UK Machine Interest • Being refined and understood – a lot of very solid expertise started this year. • Detector interest • Silicon detector: Aim to use deep-p well MAPS (INMAPS). • Other points of interest • Physics coordination, Governance committee representation, Speaker's bureau representation • UK provides 50% of the computing resources for the experiment using spare capacity from existing infrastructure. • Great starting points to build upon. • Your group is welcome to join us! Synergy via MDI Adrian Bevan

19. 1st SuperB Collaboration Meeting • http://agenda.infn.it/conferenceDisplay.py?confId=3827 Adrian Bevan

20. Summary • Major new European initiative • Significant injection of new money into our field • A new lab for HEP: • The Cabibbo Laboratory at Tor Vergata • A new light-source (not HEP, but important science) • Core UK interest exists for machine and detector. • Machine concepts have benefited other European facilities & will benefit the KEK machine. • Detector technologies can benefit CERN/JParc experiments (e.g. INMAPS) • Also "real" impact potential for world leading pixel technology • Broadest physics base of any flavour experiment proposed, or existing (see the literature): Bu,d,s, D, τ ... • More NP sensitive observables than anything else! • Great complement to existing and planned activities! Adrian Bevan

21. PHYSICS • These slides present a summary of the physics programme for SuperB. Please also see the following reports: • SuperB Progress Reports – Physics: arXiv:1008.1541 • Valencia Workshop Report: • Conceptual Design Report: arXiv:0709.0451 • New document available: • The impact of SuperB on flavour physics (you can download it from this meeting page, will be on the archive soon) • We're now starting on the Physics TDR, you're welcome to join us! Adrian Bevan

22. Data sample Adrian Bevan • ϒ(4S) region: • 75ab−1 at the 4S • Also run above / below the 4S • ~75 x109 B, D and τ pairs • ψ(3770) region: • 500fb−1 at threshold • Also run at nearby resonances • ~2 x 109 D pairs

23. τLepton Flavor Violation (LFV) Two orders of magnitude improvement at SuperB over current limits. Hadron machines are not competitive with e+e− machines for these measurements. Adrian Bevan • ν mixing leads to a low level of charged LFV (B~10−54). • Enhancements to observable levels are possible with new physics. • e− beam polarisation helps suppress background.

24. The golden LFV modes: hb • SUSY breaking scale assumed: 500GeV. SUSY breaking scale assumed: 500GeV. Current experimental limits are at the edges of the model parameter space SuperB will be able to significantly constrain these models, and either find both channels, or constrain a large part of parameter space. c/o M. Blanke Adrian Bevan

25. Bu,d physics: Rare Decays Adrian Bevan • Example: • Rate modified by presence of H+

26. Bu,d physics: Rare Decays Sensitive to models with Z penguins and RH currents. e.g. see Altmannshofer, Buras, & Straub Constraint on (ε, η) with 75ab−1 (Theoretical uncertainties) (Experimental uncertainties) Adrian Bevan • Example: • Need 75ab−1 to observe this mode. • With more than 75ab−1 we could measure polarisation.

27. Polarisation: a hint of NP? • Some anomalies in fL measured in B decays to VV final states. It has been proposed that this could be the result of NP. • SuperB will provide ample data for theorists to resolve this issue Understanding this pattern also feeds into the CKM angles programme as we need to disentangle CP odd and even states. Adrian Bevan

28. Bs physics Little Higgs (LTH) scenario Can cleanly measure AsSL using 5S data SuperB can also study rare decays with many neutral particles, such as , which can be enhanced by SUSY. Adrian Bevan

29. Charm ) Adrian Bevan • Collect data at threshold and at the 4S. • Benefit charm mixing and CPV measurements. • Also useful for measuring the Unitarity triangle angleγ (strong phase in DKππ Dalitz plot).

30. Charm • Set of new modes TDCPV @ ϒ(4S) and ψ(3770) • Null test for NP (paper discusses 36 CP eigenstates) • Tiny angle, any large CPV would be new physics. • Theoretical uncertainties will play a role probably ~1 degree. • Need to measure D to π0π0 to constrain penguin pollution (i.e. Need a Super Flavour Factory). • Can constrain CKM using weak constraint on βc,eff • Need a Super-Duper Flavour Factory to do a precision measurement of non-zero βc,eff, until then we look for NP in the up quark sector! • sin2beta is 3.2σ away from the SM (Lunghi and Soni). • Measure βc,eff to 2° at charm threshold. • Measure to 1.3° at ϒ(4S). • Evaluating penguin pollution for our next paper. • New way to measure charm mixing. e.g. 500fb-1 at charm threshold Adrian Bevan See Bevan, Inguglia, Meadows: arXiv:1106.5075

31. Precision Electroweak Measure LR asymmetry in at the ϒ(4S) to same precision as LEP/SLC at the Z-pole. Can also perform crosscheck at ψ(3770). SuperB Need to evaluate run at threshold Plot adapted from QWeak proposal (JLAB E02-020) Adrian Bevan • sin2θW can be measured with polarised e− beam • √s=ϒ(4S) is theoretically clean, c.f. b-fragmentation at Z pole

32. Interplay ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓= SuperB can measure this More information on the golden matrix can be found in arXiv:1008.1541, arXiv:0909.1333, and arXiv:0810.1312. Adrian Bevan Combine measurements to elucidate structure of new physics.

33. Precision CKM constraints The "dream" scenario with 75ab-1 Adrian Bevan • Unitarity Triangle Angles • σ(α) = 1−2° • σ(β) = 0.1° • σ(γ) = 1−2° • CKM Matrix Elements • |Vub| • Inclusive σ = 2% • Exclusive σ = 3% • |Vcb| • Inclusive σ = 1% • Exclusive σ = 1% • |Vus| • Can be measured precisely using τ decays • |Vcd| and |Vcs| • can be measured at/near charm threshold. • SuperB Measures the sides and angles of the Unitarity Triangle

34. Golden Measurements: CKM LHCb can only use ρπ βtheory error Bd βtheory error Bs Need an e+e− environment to do a precision measurement using semi-leptonic B decays. Adrian Bevan Comparison of relative benefits of SuperB (75ab-1) vs. existing measurements and LHCb (5fb-1) and the LHCb upgrade (50fb-1).

35. Golden Measurements: General Benefit from polarised e− beam very precise with improved detector Statistically limited: Angular analysis with >75ab-1 Right handed currents SuperB measures many more modes systematic error is main challenge control systematic error with data SuperB measures e mode well, LHCb does μ Clean NP search Theoretically clean b fragmentation limits interpretation Adrian Bevan

36. Physics programme in a nutshell Adrian Bevan • Versatile flavour physics experiment • Probe new physics observables in wide range of decays. • Pattern of deviation from Standard Model can be used to identify structure of new physics. • Clean experimental environment means clean signals in many modes. • Polarised e− beam benefit for τ LFV searches. • Best capability for precision CKM constraints of any existing/proposed experiment. • Measure angles and sides of the Unitarity triangle • Measure other CKM matrix elements at threshold and using τ data. • Almost all measurements will be the world best results well into the ~2030s.

39. BR Some examples... Adrian Bevan

40. Quick Comparison Belle II: Starts 2014 Integrated Lumi 50ab-1 by when? 2021 Approved by Japan Yes Host Site Yes Machine Funded Yes Detector Funding need XM€ Polarised electrons No Charm threshold No SuperB: Starts 2016 Integrated Lumi 75ab-1 by when? 2021 Approved by INFN Yes Approved by Gov. Yes Host Site Yes Machine Funded Yes Detector Funding need 25M€ Polarised electrons Yes Charm threshold Yes • SuperB is funded and is going ahead. • Results from SuperB will be more precise than any other experiment at that time. • Only 2 of the 35 golden channels will be surpassed by LHCb upgrade. • That will happen ~10 years after SuperB publishes (assuming LHCb upgrade gets funding soon). • Some measurements will be unique to SuperB: Polarisation and charm threshold running are unique features that improve the physics programme depth and impact.
