چکیده
We study the effect of SU (3) flavor breaking on high density quark matter. We discuss, in particular, the effect a non-zero electron chemical potential and a finite strange quark mass. We argue that these perturbations trigger pion or kaon condensation. The critical chemical potential behaves as µ e ∼ √ mm s ∆/p F and the critical strange quark mass as m s ∼ m 1/3 ∆ 2/3 , where m is the light quark mass, ∆ is the gap, and p F is the Fermi momentum. We note that parametrically, both the critical µ e and m 2 s /(2p F) are much smaller than the gap.

Nonperturbative self-energy of a bound quark is computed gauge-invariantly in the framework of background perturbation theory. The resulting ∆m 2 q is negative and is a universal function of string tension and current quark mass. The shift of hadron mass squared, M 2 , due to ∆m 2 q is negative, large for light quarks, and solves the long-standing problem of Regge intercepts in relativistic qua...

In this paper we present three updates to heavy flavour results from the SLD detector at SLAC. These results are preliminary, based on our full 1993-1998 dataset of 550 000 hadronic Z 0 decays produced with an average electron polarisation of 73%. The new measurements are of the hadronic branching fractions into heavy quarks (R b , Rc), the b quark asymmetry (A b) using jet charge, and the heav...

We find the finite volume QCD partition function for different quark masses. This is a generalization of a result obtained by Leutwyler and Smilga for equal quark masses. Our result is derived in the sector of zero topological charge using a generalization of the Itzykson-Zuber integral appropriate for arbitrary complex matrices. We present a conjecture regarding the result for arbitrary topolo...
