7. Research Directions: • The Wisconsin Pheno group has an international reputation • and traditional strengths in: • Collider phenomenology, perturbative QCD; • Neutrino physics; • Astroparticle physics. • We also take a leading role exploring new theories: • Supersymmetry (SUSY), SUSY GUTS, String-motivated models; • Physics with extra dimensions; • Little Higgs and strong EW dynamics; • Particle cosmology. We cover a broad range of frontier areas in HEP.

8. Neutrino physics: (Huber’s talk, Everett’s talk) • Our group continues to be one of the most productive in the world in neutrino phenomenology • Long baseline  superbeams and  beams • Reactor  oscillations • Supernova neutrinos • Lepton number violating processes (grad student) • Neutrino mass generation (grad students) • Mass varying neutrinos • Cosmogenic neutrinos (grad student) Accomplishments and on-going Work: This was a very productive 3 years; Institute staff co-authored 173 papers.

9. Higgs/EW physics and QCD: (Petriello’s talk) • Our group plays a major role in Higgs/EW physics • and QCD at colliders: • Higgs studies for the Tevatron, LHC, ILC (grad students) • Precision PDFs and electroweak physics • NLO multi-leg calculations • NNLO electroweak gauge boson production • QCD resummation (grad student) • QCD effects on new physics (grad student)

10. Beyond the SM: (Everett’s talk, Barger’s talk, Han’s talk) • Our group continues to actively explore the phenomenology of new physics models: • SUSY collider phenomenology (grad students) • Little Higgs, RS models and new particles (grad students) • Extended SUSY models with singlets: • Higgs bosons, neutralinos, Z’ (grad students) • Low scale string phenomenology • Models of fermion masses and mixings • String-motivated SUSY models • Nonstandard soft SUSY breaking scenarios

11. Astroparticle physics: (Halzen’s talk) • Our group is a world leader in theoretical studies of the physics at neutrino telescopes and more: • Cosmic neutrino phenomenology • Cosmic ray physics, gamma-ray bursts • Probe Planck-scale physics with IceCube • Detecting solar axions using Earth’s magnetic field • Cosmology: (Barger’s talk, Everett’s talk) • Our group is contributing significantly to the newly developed synergy between particle physics and cosmology: • Tests of dark energy (DE) models (grad student) • WMAP, large scale structure, and neutrinos (grad student) • Neutralino dark matter (DM) (grad student), DM-DE connections • QCD corrections to dark matter annihilation rate (grad student)

12. Other Areas: • Our group continues to contribute to other areas of phenomenology and theory as well • Novel methods for ultra-precise QFT calculations • and applications to collider physics • Numerical methods for multi-leg NLO calculations • B and D meson physics • Future colliders: ILC; gamma-gamma; muon. Our contributions to particle physics phenomenology have no boundaries.

13. Postdoc/Student Training: • Our close collaborations with graduate students and postdocs have proven to be very fruitful: • Postdocs: • Our senior postdocs all have become leaders in the field • Very good track record: • 6 of our former women postdocs hold tenured faculty positions; • 1 has a tenure-track faculty position. • Our postdocs/students from abroad have established outstanding • phenomenology programs in their home countries after training • here: Germany, Japan, UK, Taiwan, Korea, Brazil, China

14. Postdocs recently obtaining faculty positions: • P. Huber (2007): Virginia Tech • H. Davoudiasl (2006): Brookhaven L.-T. Wang (2006): Princeton T. Plehn (2005): U. Edinburgh H. Logan (2005): Carleton G. Kribs (2004): U. Oregon C. Chiang (2004): National Central U. Taiwan

15. Students: • Current senior students all have publications/submissions

16. They are active in many aspects: • Atre organized a month long seminar/colloquium series: • “Women in Theoretical Particle Physics Month” (WiTPP) • (Sally Dawson, Marcela Carena, Lynne Orr, Elizabeth Simmons) • Plans to repeat this September. • Graduate students obtaining good future opportunities: • A.

17. Impact on the Field and Community Service: Some Statistics: Since 1967 Today in academic/labs 96 PHDs 48% 68 Postdocs 74% Wisconsin Pheno Group has served as a training ground for many top phenomenologists, and thus has strong attraction for both postdocs and students. • Invited Talks: • Our faculty have presented • 186 research talks over the last 3 years • Lecture series on LHC at CERN (LHC Olympics) • as well as in Germany, China, Japan, Israel • Panel presentation at major conferences

18. Support experiments: • We provide ongoing support to experimental collaborations: • Providing our ideas, codes and results • (Tevatron, LHC, ILC, and neutrino facilities); • co-author internal experimental notes (CMS). • Conferences/Workshops: • We continue to take leadership roles as convenors/organizers: • American Linear Collider Workshop (Petriello, co-convenor) • TeV Astroparticle Physics Workshop (Halzen, co-organizer) • Aspen 2007 Summer  Workshop (Barger, co-organizer) • KITP 2008 LHC Workshop (Han, co-organizer) • Serving on numerous organizing commitees/advisory boards of international meetings

19. Local Meetings: • Since the Institute was founded in 1984, sponsored 25 symposia/ workshops in phenomenology: • Annual Pheno Symposia are venue for young physicists to interact with senior physicists and have become a very popular event in the particle physics community. • In Pheno 07, 200 participants and 138 talks! • (way above the normal 130 participants of a few years ago.) • Host of the CTEQ Summer School (in alternate years) • Petriello joins CTEQ, serves as local organizer.

20. Now the individual presentations … • Lisa Everett: Physics Beyond the Standard Model in the LHC Era • Vernon Barger: TeV Physics and Dark Matter • Francis Halzen: Neutrino Astronomy • Patrick Huber: The Future US Long Baseline Neutrino Program • Thomas McElmurry: … • Kathryn Zurek: Exotic Signatures at the LHC • Tao Han: Top Quark as a Window to New Physics • Frank Petriello, Task Q (OJI Award): QCD Phenomenology
