Towards compressed baryonic matter densities: D meson diffusion
arXiv:2607.14058
The paper calculates how D mesons move and spread in dense nuclear matter by evaluating their diffusion and momentum transport coefficients using kinetic theory and a chiral SU(3) hadronic model.
Abstract
We study the spatial diffusion coefficient and the momentum transport coefficients of D mesons through a dense nuclear medium in the relaxation time approximation of the kinetic theory. The in medium modifications of the D meson transport properties are computed in the chiral SU(3) hadronic model. Relaxation time is estimated using dilute and degenerate gas approximations for low and high baryonic densities, respectively. We have noticed that relaxation time and spatial diffusion of D meson decrease rapidly in the low density dilute gas domain and mildly in the high density degenerate gas domain. The detailed result of the present work on D meson diffusion is quite contemporary and important towards the compressed baryonic matter densities which can be assessed in future heavy ion collision experiments.
