# Quark mass dependence of the low-lying charmed mesons at one loop in HH$\chi$PT

## TL;DR

This paper investigates how light and heavy quark masses influence low-lying charmed mesons using one-loop heavy-hadron chiral perturbation theory, fitting lattice QCD data to determine relevant constants.

## Contribution

It introduces a systematic approach to extract low energy constants from lattice data and discusses discretization effects related to charm quark mass.

## Key findings

- Determined low energy constants from lattice QCD data.
- Analyzed discretization effects due to charm quark mass.
- Enhanced precision in modeling charmed meson mass dependence.

## Abstract

We study the light and heavy quark mass dependence of the low-lying charmed mesons in the framework of one-loop HH$\chi$PT. The low energy constants are determined by analyzing the available lattice data from different LQCD simulations. Model selection tools are implemented to determine the relevant parameters as required by data with a higher precision. Discretization and other effects due to the charm quark mass setting are discussed.
