DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HoloTube/13/
 ">A new hydrodynamics with spin formalism for the description of polarizat
 ion effect of Lambda hyperons</a>\nby Rajeev Singh (Institute of Nuclear P
 hysics Polish Academy of Sciences) as part of HoloTube: Applied holography
  webinars\n\n\nAbstract\nMeasurements made recently by the STAR collaborat
 ion show that the Lambda hyperons produced in relativistic heavy-ion colli
 sions are subject to global spin polarization with respect to an axis coin
 cident with the axis of rotation of the produced matter. Recently formulat
 ed formalism of relativistic hydrodynamics with spin\, which is a generali
 zation of the standard hydrodynamics\, is a natural tool for describing th
 e evolution of such systems. This approach is based on the conservation la
 ws and the form of the energy-momentum tensor and spin tensor postulated b
 y de Groot\, van Leeuwen\, and van Weert (GLW). Using Bjorken symmetry we 
 show how this formalism may be used to determine observables describing th
 e polarization of particles measured in the experiment.\n
