Chiral symmetry restoration with three chiral
partners
Juan Torres-Rincon
I consider masses of chiral partners in
the context of the chiral symmetry restoration at finite temperature.
Using an effective quark model I first review the standard situation where
two mesonic chiral partners become nearly degenerate when temperature is
increased above the chiral restoration one. Then I turn to an effective
hadron theory to describe charm mesons where the chiral companion of the D
meson is generated dynamically as a "double pole structure". In such a
case three different masses are to be analyzed as functions of the
temperature. I suggest a possible restoration pattern at high temperature
when the back-reaction of the quark condensate is incorporated.
