Electromagnetic spectral function and dilepton rate in a hot magnetized QCD medium

Understand

The dilepton production rate in hot QCD medium is studied within a effective description of the medium in the presence of magnetic field.

• This could be done by obtaining the one-loop self energy of photon due to the effective (quasi-) quark loop at finite temperature under an arbitrary external magnetic field while employing the real time formalism of Thermal Field Theory.
• The effective quarks and gluons encode hot QCD medium effective in terms of their respective effective fugacities.
• The magnetic field enters in the form of landau level quantization, in the matter sector (quarks, antiquarks).
