Effect of magnetic field on dilepton production in a hot plasma

Aritra Bandyopadhyay, S. Mallik

Noncentral collision of heavy ions can generate large magnetic field in its neighbourhood. We describe a method to calculate the effect of this field on the dilepton emission rate…

Rho meson decay in presence of magnetic field

Aritra Bandyopadhyay, S. Mallik

We find a general expression for the one-loop self-energy function of neutral -meson due to intermediate state in a background magnetic field, valid for arbitrary magni…

Evaluating transport coefficients in real time thermal field theory

S. Mallik, Sourav Sarkar

Transport coefficients in a hadronic gas have been calculated earlier in the imaginary time formulation of thermal field theory. The steps involved are to relate the defining retar…

Relativistic spectral function of nucleon in hot nuclear matter

Sabyasachi Ghosh, S. Mallik, Sourav Sarkar

We present a simple calculation of the nucleon self-energy in nuclear matter at finite temperature in a relativistic framework, using the real time thermal field theory. The imagin…

Analytic structure of rho meson propagator at finite temperature

Sabyasachi Ghosh, S. Mallik, Sourav Sarkar

We analyse the structure of one-loop self-energy graphs for the rho meson in real time formulation of finite temperature field theory. We find the discontinuities of these graphs a…

QCD sum rule for nucleon in nuclear matter

S. Mallik, Sourav Sarkar

We consider the two-point function of nucleon current in nuclear matter and write a QCD sum rule to analyse the residue of the nucleon pole as a function of nuclear density. The nu…
