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…
Neutrino-antineutrino synchrotron emission from magnetized dense quark matter
Ritesh Ghosh, Igor A. Shovkovy
Using the Kadanoff-Baym formalism, we perform a detailed study of neutrino-antineutrino synchrotron emission from strongly magnetized, dense quark matter under conditions relevant…
Shear and bulk viscosity for a pure glue theory using an effective matrix model
Manas Debnath, Ritesh Ghosh, Najmul Haque +2
At nonzero temperatures, the deconfining phase transition can be analyzed using an effective matrix model to characterize the change in holonomy. The model includes gluons and two-…
Neutrino energy and momentum emission from magnetized dense quark matter
Ritesh Ghosh, Igor A. Shovkovy
Using first-principles field-theoretic methods, we investigate neutrino emission from strongly magnetized dense quark matter under conditions relevant to compact stars. We develop…
Anisotropic charge transport in strongly magnetized relativistic matter
Ritesh Ghosh, Igor A. Shovkovy
We investigate electrical charge transport in hot magnetized plasma using first-principles quantum field theoretical methods. By employing Kubo's linear response theory, we express…
Electrical conductivity of hot relativistic plasma in a strong magnetic field
Ritesh Ghosh, Igor A. Shovkovy
We employ first-principles quantum field theoretical methods to investigate the longitudinal and transverse electrical conductivities of a strongly magnetized hot quantum electrody…
The fermion self-energy and damping rate in a hot magnetized plasma
Ritesh Ghosh, Igor A. Shovkovy
We derive a general expression for the fermion self-energy in a hot magnetized plasma by using the Landau-level representation. In the one-loop approximation, the Dirac structure o…
Energy loss of a fast moving parton in Gribov-Zwanziger plasma
Manas Debnath, Ritesh Ghosh, Mohammad Yousuf Jamal +2
The Gribov-Zwanziger prescription applied within Yang-Mills theory is demonstrated to be an efficient method for refining the theory's infrared dynamics. We study the collisional e…
