Radiative lepton flavor violating B, D, and K decays

Abstract

We argue that radiative lepton flavor violating (RLFV) decays $P\to \gamma {\ell }_1{\overline{\ell }}_2$ of $P=B_q^0$, ${\bar{D}}^0$, and $K^0$ meson states are robust probes of new physics models. In particular, they could be used to put constraints on the Wilson coefficients of effective operators describing lepton flavor-changing neutral current interactions at low energy scales. We set up a generic framework for describing these transitions and review new physics constraints from $P\to {\ell }_1{\bar{\ell }}_2$ decays. There is discussion of how RLFV transitions provide access to the operators that cannot be constrained in two-body decays and we in turn motivate further experimental searches via these channels.
