Contribution

It introduces a transport equation approach to model dimuonium motion and links its transverse energy distribution to plasma characteristics.

Findings

Dimuonium production yield is low but informative.

Transverse energy distribution reflects plasma conditions.

Transport modeling provides insights into quark-gluon plasma dynamics.

Abstract

We study dimuonium $(\mu^+\mu^-)$ production in the quark-gluon plasma created in relativistic heavy ion collisions. The production is controlled by the process $q\bar q\rightarrow (\mu^+\mu^-)g$, and the dimuonium motion in the plasma is described by a transport equation. While the electrodynamics dominated dimuonium yield is not high enough, the transverse energy distribution carries the information of the plasma at RHIC and LHC energies.
