Title: Recent developments of spin physics in relativistic heavy ion
collisions

 

Abstract: Spin is a relatively new topic in the rather mature field of
relativistic heavy ion collisions and it has attracted much interest
over the past few years. The predictions of the hydrodynamic model of
the Quark Gluon Plasma have been confirmed by the measurements of
global spin polarization of Lambda hyperons. However, the measurements
of spin polarization as a function of the hyperon momentum revealed
consistent discrepancies with respect to the theoretical predictions.
In this talk, I will first present some recent theoretical developments
which imply a solution of the local polarization puzzles.
In the second part, I will show that spin can be used as a probe of
local parity violation in heavy ion collisions, an effect which has
been long sought through the well known Chiral Magnetic Effect. By
measuring Lambda helicity correlation as a function of the difference
of their azimuthal angles, it is in principle possible to find an
evidence of local parity violation without the involvment of the
electro-magnetic field.
