Contribution

It introduces a one-parameter class of regularizations for the Nonconfining Schwinger Model and analyzes its phase space and physical properties.

Findings

Gauge boson mass depends on regularization parameters

Deconfinement scenario clarified at the quark-antiquark potential level

Phase space structure determined for the generalized model

Abstract

Nonconfining Schwinger Model [AR] is studied with a one parameter class of kinetic energy like regularization. It may be thought of as a generalization over the regularization considered in [AR]. Phasespace structure has been determined in this new situation. The mass of the gauge boson acquires a generalized expression with the bare coupling constant and the parameters involved in the regularization. Deconfinement scenario has become transparent at the quark-antiquark potential level.
