Impact of longitudinal bulk viscous effects to heavy quark transport in a strongly magnetized hot QCD medium

Understand

The effects of longitudinal bulk viscous pressure on the heavy quark dynamics have been estimated in a strongly magnetized quark-gluon plasma within the Fokker-Planck approach.

• The bulk viscous modification to the momentum distribution of bulk degrees of freedom has been obtained in the presence of a magnetic field while incorporating the realistic equation of state of the hot magnetized QCD medium.
• As the magnetic field breaks the isotropy of the medium, the analysis is done along the directions longitudinal and transverse to the field.
• The longitudinal bulk viscous contribution is seen to have sizable effects in the heavy quark momentum diffusion in the magnetized medium.
