   The phase transition in QCD with broken SU(2) flavour symmetry

   Rajiv V. Gavai🇮🇳 · Sourendu Gupta🇮🇳

   We report the first investigation of the QCD transition temperature, T_c, for two flavours of staggered quarks with unequal masses at lattice spacings of 1/4T. On changing the u/d quark mass ratio in such a way that m(pi_0)^2/m(pi_+)^2 changes from 1 to 0.78, thus bracketing the physical value of this ratio, we find that T_c remains unchanged in units of both m_rho and Lambda_MSbar.

   Spectrum of screening masses in the (3+1)D SU(2) pure gauge theory near the critical temperature

   Roberto Fiore🇮🇹 · Alessandro Papa🇮🇹 · Paolo Provero🇮🇹

   We study the spectrum of screening masses in the deconfined phase of (3+1)D SU(2) pure gauge theory near criticality and compare it with the spectrum of bound states in the broken symmetry phase of the 3D Ising model, which is related to the gauge theory by universality.

   Numerical results from large N reduced QCD_2

   J. Kiskis · R. Narayanan. H. Neuberger

   Some results in QCD_2 at large N are presented using the reduced model on the lattice. Overlap fermions are used to compute meson propagators.

   Baryons in Partially-Quenched Chiral Perturbation Theory

   Martin J. Savage🇺🇸

   I discuss the inclusion of baryons into partially-quenched chiral perturbation theory and describe one-loop calculations that have been performed.
