Title of Talk: Spin physics in heavy ion collisions and in the Quark-Gluon plasma
Abstract: This talk will provide a smattering of the physics of spin and polarization in relativistic fluids, with applications to the Quark-Gluon Plasma (QGP) created in heavy ion collisions. The QGP is a strongly interacting relativistic fluid reminiscent of the state of the universe microseconds after the Big Bang. When produced experimentally in peripheral nuclear collisions, the angular momentum of the QGP is expected to polarize particles when it eventually breaks down into hadrons. I will discuss how to deal with this phenomenon focusing on the $\Lambda$ polarization and the vector meson spin alignment, the two main observables to date. After introducing these quantities, I will qualitatively show how to address their calculation using a quantum-relativistic framework based on the relativistic density operator.
Venue (HYBRID-EVENT): Goldene Box, Physikalisches Institut, INF 226, 69120 Heidelberg AND all talks will also be streamed via the permanent Zoom-link:
