On the Chiral Perturbation Theory for Two-flavor Two-color Qcd at Finite Chemical Potential
The phase diagram of quantum chromodynamics (QCD) has attracted much attention in recent years. The region of high baryon density and low temperature is relevant for the description of deconfined quark matter, which can be found in the centers of neutron stars. It is expected to exhibit a variety of color-superconducting phases.1 Unfortunately, there is only very little firm knowledge concernin...
متن کاملMeson Mass at Large Baryon Chemical Potential in Dense QCD
We reexamine the quark mass induced term in chiral Lagrangian in color-flavor locking phase in dense QCD, and show that the meson mass term is determined by three independent invariants under chiral-axial symmetry, and is given in terms of the quark mass, gap, and the chemical potential by mπ ∼ mq∆/μ ln(μ2/∆2). Thus mesons become massless as μ → ∞. Cold, dense quark system with three massless q...
متن کاملCenter-symmetric effective theory for two-color QCD with massive quarks at nonzero chemical potential
We revisit the center-symmetric dimensionally reduced effective theory for two-color Yang–Mills theory at high temperature. This effective theory includes an order parameter for center symmetry breaking/restoration and thus allows to broaden the range of validity of the conventional threedimensional effective theory (EQCD) to lower temperatures, towards the confining phase transition. We extend...
متن کاملTwo Colours Qcd at Nonzero Chemical Potential
We identify the Goldstone modes appropriate to the low and high density phases of SU(2) lattice gauge theory with staggered fermions. We present hybrid Monte Carlo simulation results for susceptibilities on a 6 lattice at β = 1.5, m = 0.05. We specify how to implement a diquark source term in a lattice simulation and present first measurements of the lattice diquark condensate as a function of ...
متن کاملReal and Imaginary Chemical Potential in 2-color Qcd
In this paper we study the finite temperature SU(2) gauge theory with staggered fermions for non-zero imaginary and real chemical potential. The method of analytical continuation of Monte Carlo results from imaginary to real chemical potential is tested by comparison with simulations performed directly for real chemical potential. We discuss the applicability of the method in the different regi...
