Hunting for Superstrong Magnetic Fields in Heavy-Ion Collisions | Colóquio do DFMA

Resumo: Heavy-ion collisions provide a unique opportunity to investigate the deconfined phase of strongly interacting matter that is believed to have filled the Universe during its initial stage after the Big Bang. The system created in these collisions behaves as an almost perfect fluid composed of quarks and gluons at extremely high temperatures and densities. In addition, non-central heavy-ion collisions are expected to generate some of the strongest magnetic fields known in nature. Despite significant theoretical and experimental efforts over the past decade, a clear and unambiguous signature of these magnetic fields has yet to be established. Understanding their effects on the quark-gluon
plasma remains one of the major challenges in the field. In this talk, I will review the basic properties of the quark-gluon plasma and discuss possible consequences of the interplay between strong and electromagnetic interactions in heavy-ion collisions. I will also present our proposal for an observable that may provide direct information about the magnetic field generated in these events.
