Novel loop-diagrammatic approach to QCD θ parameter and application to the left-right model
Abstract When the QCD axion is absent in full theory, the strong CP problem has to be explained by an additional mechanism, e.g., the left-right symmetry. Even though tree-level QCD θ ¯ $$ \overline{\theta} $$ parameter is restricted by the mechanism, radiative corrections to θ ¯ $$ \overline{\theta...
