Diffusion of Lambda(c) in hot hadronic medium and its impact on Lambda(c)/D ratio

The drag and diffusion coefficients of the

Dragging D mesons by hot hadrons

{\mathrm{\ensuremath{\Lambda}}}_{c}(2286\text{ }\text{ }\mathrm{MeV})

Nucleon thermal width owing to pion-baryon loops and its contributions to shear viscosity

have been evaluated in the hadronic medium which is expected to be formed in the later stages of the evolving fireball produced in heavy ion collisions at RHIC and LHC energies. The interactions between the

Shear viscosity due to Landau damping from the quark-pion interaction

{\mathrm{\ensuremath{\Lambda}}}_{c}

Shear and bulk viscosities of quark matter from quark-meson fluctuations in the Nambu–Jona-Lasinio model

and the hadrons in the medium have been derived from an effective hadronic Lagrangian, as well as from the scattering lengths obtained in the framework of heavy baryon chiral perturbation theory (

). In both the approaches, the magnitude of the transport coefficients turn out to be significant. A larger value is obtained in the former approach with respect to the latter. Significant values of the coefficients indicate a substantial amount of interaction of the
