# Effect of magnetic field on dilepton production in a hot plasma

## TL;DR

This paper investigates how strong magnetic fields in heavy ion collisions influence dilepton production rates in a hot plasma, revealing significant effects at lower dilepton momenta using thermal field theory.

## Contribution

It introduces a real-time thermal field theory method to quantify magnetic field effects on dilepton emission in heavy ion collisions.

## Key findings

- Magnetic fields significantly alter dilepton rates at low momenta
- The method accurately captures magnetic effects in thermal equilibrium
- Dilepton production is sensitive to magnetic field strength in the plasma

## Abstract

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 from the colliding region, when it reaches thermal equilibrium. It is calculated in the real time method of thermal field theory. We find that the rate is affected significantly only for lower momenta of dileptons.
