Prof. Alex Kovner, Univ. of Connecticut
Monopoles and Confinement
Abstract:
I discuss some worrying aspects of
the monopole mechanism of confinement in QCD. In particular I point out
that in SU(2) pure gauge theory the magnetic charge operator cannot be
defined in principle. I also describe the perturbative calculation of
the expectation value of the monopole creation operator in the
confining phase of the Georgi-Glashow model.
All are welcome. Tea/coffee and biscuits to follow. For directions to
