Double Delight in PSR J0737-3039 Quark-Deconfinement Nova model

- First ever observed Double Pulsar System, Burgay et al., Nature 426 (2003) 531
- Keplerian parameters Porb=2.45 h, ap , e = 0.088,and To measured from the pulsar timing data.
- Pulsar A has a spin period 22.7 ms and M=1.337 M; those of Pulsar B are 2.8 s and M= 1.25 M ,
- Accurate measurements of relativistic corrections to the Keplerian description,
- Enormous bursts of gravitational waves.

Best EXO- fit values: R =11.5 km, but M=1.8M = SQS!?

- Allowed EOS : M max theo> M highest obs
Hulse-Taylor pulsar , Mobs= 1.44 M

- Softer EOS ruled out by EXO 0748-676!

Lattice QCD Quark-Deconfinement Nova model

- Order of Phasetransition?
- Speed of sound?

QCD phase diagram Quark-Deconfinement Nova model

Taylor series: order 8

Large lattices required:

L > 6/m_pi, to avoid large finite size effects

Small quark masses:

M_pi/m_rho=0.31

Critical endpoint!

The demise of the Structure function: R. Venugopalan Quark-Deconfinement Nova model

- Dipoles (and multipole) operators may be more
relevant observables at high energies

- Are universal-process independent.
- RG running of these operators - detailed tests of
high energy QCD.

model based on above physics + add valence quark contribution

Peeking through the Colored Looking Glass Quark-Deconfinement Nova model

A perspective on Future Directions?

Color Glass Condensate as Medium:

Pomerons, Odderons, Reggeons as Quasiparticle excitations of the CGC

-> ODD Couplerons develop: Larry, marrying with Klaus Werner??

Ploops: (Pomeron loops) How a little fluctuation becomes a big problem

The CGC and the QGP: Is the sQGP really the CGC? Is rapid “thermalization” due to the CGC? Does flow arise largely from the CGC?

Fluctuation studies Quark-Deconfinement Nova model

KOCH‘s

- K/p fluctuations increase towards lower beam energy
- Significant enhancement over hadronic cascade model

- p/p fluctuations are negative
- indicates a strong contribution from resonance decays

Summary of Lee’s Talk Quark-Deconfinement Nova model

- Reported on the QCD NLO Quarkonium- Gluon/hadron dissociation cross section.
Large correction even for upsilon system, especially near threshold

2. The corrections becomes smaller with thermal quark and gluon mass of larger than 200 MeV

Thermal width of J/y : 1 GeV at T=600 [email protected] 1mb

3. The dissociation cross section due to quarks are less than 10 % of that due to the gluons.

The quenched lattice calculation of the mass and width of J/y at finite temperature should be reliable.

Strangeness Quark-Deconfinement Nova model

- Rafelski
- Cleymans
- Braun Munzinger
- Bleicher

Where do we expect Quark-Deconfinement Nova modelinteresting effects?

- 1st Order phase transition at high mueB
- No P.T. at low mueB: Xing
- Search for irregularities around E beam = 10-40 GeV:
- Flow, strangeness, E-by-E

Plot from L. Bravina and E. Bratkovskaya shown in Bleicher’s talk

Transport theory: AA Strangeness Excitation functions Quark-Deconfinement Nova modelBleicher’s & Rafelski’s talk

- 4 pi and mid-y abundancies: OK
But not K+/pi!

- Energy dependence: OK
- Hadron-string models work well

Jetquenching in medium [email protected] RHIC Quark-Deconfinement Nova model but: Open Questions..

- How much of jet quenching due to JET->Hadron coll?
- Measure leading particle kind & p-tot -
- Different X-sections – different quenching...
- Jets thru equilibrized plasma-> Machshock in Plasma!
- What is the sound velocity of the medium ?
- Use jet-induced Mach-cones -> c_s of plasma !

Rescattering !

Plasma suppression

Correlated Jets: Transport model prediction Quark-Deconfinement Nova modelHow much of Jet quenching is due to (pre-) hadronic FSI ?

- p-p jet angular correlations o.k.
- near-side jet angular correlation o.k. for central Au+Au
- 50% too little suppression of away-side jet by hadrons !
- 50% QGP needed !
