چکیده
We determine the curvature of the phase transition line in the μ −T plane through an analysis of various observables, including the Polyakov loop, the quark number susceptibilities and the susceptibility of the chiral condensate. The second derivative of these quantities with respect to μ was calculated. The measurements were carried out on NT = 4,6,8 and 10 lattices generated with a Symanzik improved gauge and stout-link improved 2+1 flavour staggered fermion action using physical quark masses.

The finite temperature QCD transition for physical quark masses is a crossover. For smaller quark masses a first-order phase transition is expected. Using Symanzik improved gauge and stout improved fermion action for 2+1 flavour staggered QCD we give estimates/bounds for the phase line separating the first-order region from the crossover one. The calculations are carried out on two different la...

are calculated on the RBC/UKQCD 32 3 × 64, L s = 16 lattices, using 2+1 dynamical flavors and domain wall fermions, with an inverse lattice spacing of a −1 = 2.42(4) GeV. Data is interpolated or extrapolated to energy conserving kinematics and a preliminary calculation of the experimental parameter |A 2 | is performed.

Numerical studies support the conjecture that in continuum planar QCD the eigenvalue density of a Wilson loop operator undergoes a transition as the loop is dilated while keeping the loop shape fixed. A second part of the conjecture is that the transition obeys large N universality and that this universality class is the same in 2, 3 and 4 Euclidean space-time dimensions. The focus of the talk ...
