Effective Chiral Symmetry Restoration for Heavy-Light Mesons

Published 27 Apr 2014 in hep-ph and nucl-th | (1404.6787v1)

Abstract: We study the spectrum of heavy-light mesons within a model with linear instantaneous confining potential. The single-quark Green function and spontaneous breaking of chiral symmetry are obtained from the Schwinger-Dyson (gap) equation. For the meson spectrum we derive a Bethe-Salpeter equation (BSE). We solve thiss equation numerically in the heavy-light limit and obtain effective restoration of chiral and $U(1)_A$ symmetries at large spins.
