Noncommutative SU ( N ) gauge theory and asymptotic freedom

Noncommutative SU ( N ) gauge theory and asymptotic freedom

In this paper we analyze a version of the SU(N) gauge theory on noncommutative space-time which is one-loop renormalizable to first order in the expansion in the noncommutativity parameter {theta}. The one-loop renormalizability is obtained through the modification of the initial 'minimal'...

Zusammenfassung:In this paper we analyze a version of the SU(N) gauge theory on noncommutative space-time which is one-loop renormalizable to first order in the expansion in the noncommutativity parameter {theta}. The one-loop renormalizability is obtained through the modification of the initial 'minimal' action, with the gauge fields in the adjoint representation of SU(N), and by the renormalization of the noncommutativity parameter {theta}.
