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. |
