TOPOLOGICAL SUSCEPTIBILITY IN A NONLOCAL CHIRAL QUARK MODEL

A. E. Dorokhov

The topological susceptibility is studied in the framework of a covariant chiral quark model with nonlocal quark-quark interaction. The relation of the first moment of topological susceptibility c'(0) and the "spin crisis" problem is briefly discussed. It is shown, in particular, that one always gets the inequality c'(0) >c'OZI.
