BPS ansatzes as electric form-factors

High Energy Physics - Theory 2021-12-07 v5

Abstract

We argue that BPS ansatzes, entering manifestly vacuum BPS monopole solutions to equations of motion in the (Minkowskian) non-Abelian Higgs model play the role of some electric form-factors and that this implies (soft) violating the CP-invariance of the mentioned model, similar to taking place in the Euclidian Yang-Mills (YM) theory with instantons, generating the θ\theta-term in the appropriate effective Hamiltonian.
