# Thermal D mesons from anisotropic lattice QCD

## TL;DR

This study investigates the behavior of open charm mesons near the QCD deconfinement transition using anisotropic lattice QCD, revealing dissociation close to Tc and mass shifts below it, with quark flavor influencing thermal modifications.

## Contribution

First lattice QCD analysis of open charm mesons' correlators and spectral functions across the deconfinement transition with anisotropic lattices.

## Key findings

- D mesons dissociate near the crossover temperature Tc.
- Thermal D meson mass shifts are observed below Tc.
- Strange quark mesons show smaller thermal modifications.

## Abstract

We present results for correlators and spectral functions of open charm mesons using 2+1 flavours of clover fermions on anisotropic lattices. The D mesons are found to dissociate close to the deconfinement crossover temperature Tc. Our preliminary results suggest a shift in the thermal D meson mass below Tc. Mesons containing strange quarks exhibit smaller thermal modifications than those containing light quarks.
