Description
We consider new contributions of lepton and nucleon EDM, which are
given by background effects of ultralight bosons. We calculate EDM contributions up to two loop diagram for CP-violating ALPs interactions with photon, lepton and nucleon. These new contributions will give new constraints on couplings, and constraints would be stronger if ALP mass is smaller than $10^{−11}$ eV.
