Impact of a thermal medium on D mesons and their chiral partners

# metadata.dc.description.abstract[].value
We study D and Ds mesons at finite temperature using an effective field theory based on chiral and heavy-quark spin-flavor symmetries within the imaginary-time formalism. Interactions with the light degrees of freedom are unitarized via a Bethe-Salpeter approach, and the D and Ds self-energies are calculated self-consistently. We generate dynamically the D*0(2300) and Ds*(2317) states, and study their possible identification as the chiral partners of the D and Ds ground states, respectively. We show the evolution of their masses and decay widths as functions of temperature, and provide an analysis of the chiral-symmetry restoration in the heavy-flavor sector below the transition temperature. In particular, we analyse the very special case of the D-meson, for which the chiral partner is associated to the double-pole structure of the D*0(2300).
