Description

Inspired by a recent observation of enhancement in the dilepton rate from a magnetized QCD medium [1], we utilize a hydrodynamic model framework to incorporate the impact of the space-time evolution of the system on such properties [2]. In particular, we investigate the transverse momentum ($p_T$) spectra and even flow harmonics such as $v_2$ and $v_4$ with a focus on the impacts of the strength and lifetime of the magnetic field. We find that there is an enhancement in the $p_T$ spectra in the presence of the external field, which grows with its strength. Another interesting observation is the existence of nonzero flow harmonics in the presence of even a very weak magnetic field. Such observations allow one to consider dileptons as a strong candidate for use as a magnetometer for a hot and magnetised QGP.
