- W2542142008 abstract "Violation of $CP$ invariance is a quite relevant phenomenon that is found in the Standard Model (SM), though in small amounts. This has been an incentive to look for high-energy descriptions in which $CP$ violation is increased, thus enhancing effects that are suppressed in the SM, such as the electric dipole moments (EDMs) of elementary particles. In the present investigation, we point out that charged currents in which axial couplings are different from vector couplings are able to produce one-loop contributions to EDMs of charged leptons if neutrinos are massive and if these currents violate $CP$. We develop our discussion around charged currents involving heavy neutrinos and a $W'$ gauge boson coupling to SM charged leptons. Using the most stringent bound on the electron EDM, provided by the ACME Collaboration, we determine that the upper bound on the difference between axial and vector currents lies within $sim10^{-10}$ and $sim10^{-7}$ for heavy-neutrino masses between $0.5,{rm TeV}$ and $6,{rm TeV}$ and if the $W'$ mass is within $0.45,{rm TeV}-7,{rm TeV}$. This possibility is analyzed altogether with the anomalous magnetic moments of charged leptons, among which we estimate, for the $tau$ lepton, an anomalous magnetic moment contribution between $sim10^{-8}$ and $sim10^{-10}$ for neutrino masses ranging from $0.5,{rm TeV}$ to $6,{rm TeV}$ and a $W'$ mass between $0.45,{rm TeV}$ and $7,{rm TeV}$. The general charged currents are also used to calculate the branching ratio for $muto egamma$, which gets suppressed if the set of masses of heavy neutrinos is quasidegenerate. In a scenario of nondegenerate neutrino masses, we find that regions of neutrino and $W'$ masses in which the contributions to this flavor changing branching ratio are lower than the current upper bound exist. We show that such regions can be widened if the $W'$ gauge boson mass is larger." @default.
