Beyond leading-logarithm photon production from two-loop diagrams in a hot QCD medium
Sumit, Ritesh Ghosh, Munshi G. Mustafa
We investigate high-energy photon production from a quark-gluon plasma by evaluating the imaginary part of the two-loop photon self-energies in thermal QCD. Working within the imag…
Magnetized bottom-up thermalization in heavy-ion collisions
Ritesh Ghosh, Igor A. Shovkovy
We investigate how a strong magnetic field generated in noncentral heavy-ion collisions may modify the bottom-up equilibration scenario. In the conventional weak-coupling picture,…
Neutrino production mechanisms in strongly magnetized quark matter: Current status and open questions
Igor A. Shovkovy, Ritesh Ghosh
We review the main neutrino emission mechanisms operating in dense quark matter under strong magnetic fields, with particular emphasis on conditions expected in the interiors of co…
Magnetoviscosity of relativistic plasma
Ritesh Ghosh, Igor A. Shovkovy
Using first-principles quantum field-theoretical methods, we investigate the shear and bulk viscosities of strongly magnetized relativistic plasmas. The analysis is performed withi…
Quarkonium in a QCD medium with momentum-dependent relaxation time
Sunny Kumar Singh, Samapan Bhadury, Ritesh Ghosh +1
In this study, we explore the properties of quarkonia in a hot QCD medium using a newly proposed collision kernel that consistently incorporates the particle's momentum dependence…
Review of heat and charge transport in strongly magnetized relativistic plasmas
Igor A. Shovkovy, Ritesh Ghosh
We review field-theoretic studies of charge transport in hot relativistic plasmas under strong magnetic fields and extend the analysis to thermal conductivity. The calculations rel…
