Abstract for a Poster

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 ̄ parameter is restricted by the mechanism, radiative corrections to θ ̄ are mostly
generated, which leads to a dangerous neutron electric dipole moment (EDM). The ordinary
method for calculating the radiative θ ̄...
