Abstract. We investigate the dependence of both light and heavy quark masses on the properties of low-lying charmed mesons within the framework of one-loop HHX PT. Determination of the low energy constants is accomplished through an analysis of lattice data obtained from various Lattice Quantum Chro-modynamics (LQCD) simulations. Model selection tools are employed to identify the pertinent parameters needed to achieve higher precision alignment with the data. Our study extends to the analysis of HSC energy levels for DK scattering in I = 0, considering different boosts and two pion masses. A comprehensive global fit is performed, incorporating HSC energy levels along with those from DK and D* K scattering obtained from RQCD and Prelovsek et al. Finally, we extract the dependence of D*s0(2317) and Ds1(2460) resonances on the pion mass.
