Abstract:
The quark-gluon plasma (QGP) produced in ultra-relativistic heavy-ion collisions is well described by relativistic hydrodynamics. Non-central collisions are characterized by very large angular momentum, which in a fluid system manifests as flow vorticity. This rotational structure can lead to spin polarization of produced hadrons, and their global polarization along the angular momentum can be measured in experiments. In this talk, I will present the recent results on the global polarization of hyperons in Au+Au collisions measured by the STAR experiment at RHIC.
Important: This seminar is held in building D-11 room 104.
Please, be advised that due to the pandemic sanitary rules, we can absorbe 1 unvaccinated person per 10m^2, which means 4 people. As most of us are vaccinated, this should not be a problem. There will be a list of participants, stating that they were (or were not) vaccinated / are immune / with a valid covid test, where we will ask you to sign in upon arrival. Also, people with ANY symptoms of cold (either of running nose, cough, temperature, ...), not necessarily covid, are not allowed to participate according to the rules. We hope you understand. The situation is dynamic and we will of course keep you posted. At the moment we plan to proceed “live”, similary to teaching at AGH.
