Abstract: (APS)
We compute the qiqjγ transition amplitude for off-shell and on-shell quarks with flavors i≠j, in the standard weak-interaction model. The results we present are valid for all quark and photon momenta and for all external and internal quark masses. We discuss the Feynman rules and Ward-Takahashi identities in the 't Hooft—Feynman gauge. Our results can be applied to a variety of phenomena such as the electric dipole moment of the neutron, the process e+e−→tc¯, and flavor-changing transitions with either gluon or photon emission.- QUARK: OFF-SHELL
