Description

Hadron physics

Summary

We will present results for the temperature dependence of the masses of $D^+$, $D^+_s$, $D^{*+}$, $D^{*+}_s$ and also the hidden charm mesons $\eta_c$, $J/\psi$ as well as the light mesons $\pi$, $K$ and $\eta$. In order to do that, we use the NJL-model with a symmetry preserving-regularization method of the ultraviolet divergences. The regularization method is based on a subtraction scheme that avoids standard steps in the evaluation of divergent integrals that invariably lead to symmetry violation. At zero temperature this approach has already been applied successfully in the computation of masses and decay constants of heavy-light mesons, where we have found a correct trend in the decay constants contrary to the results using the standard approach to handle divergent integrals in NJL-model and also with Bethe-Salpeter computations. The aim of this computation is study charm mesons diffusion in mesonic matter, where for instance, we can be able to compute the drag and diffusion coefficients of $D^+$ in hadronic medium.
