Chiralspin symmetry and its implications for QCD
Speaker:Leonid Glozman (Uni Graz)
Abstract:The QCD Lagrangian is chirally invariant. However the charge operator and the chromo-electric interaction in QCD have in addition the chiralspin symmetry that allows mixing of the left and right quarks. The chromo-magnetic interaction and the quark kinetic term break this symmetry. Hadrons at zero temperature with truncated near-zero modes of the Dirac operator show both chiral and chiralspin symmetries. This means that the near-zero modes are responsible not only for chiral symmetry breaking but also for the chiralspin breaking via the chromo-magnetic effects. This implies that elementary objects in QCD at high temperatures are chiral quarks bound by the pure chromo-electric field, without any magnetic effects. This picture is radically different from the quark-gluon plasma scenario.
