Topological charge and topological susceptibility in connection with translation and gauge invariance
It is shown that the evaluation of the expectation value (EV) of topological charge density over theta vacuum is reduced to investigation of the Chern-Simons term EV. An equation for this quantity is established and solved. EV of the topological charge density at an arbitrary theta occurs to be equa...
