abstract
We study charged lepton flavor violation associated with a light leptophilic axion-like particle (ALP), $X$, at the $B$-factory experiment Belle II. We focus on production of the ALP in the tau decays $\tau \to X l$ with $l=e,\mu$, followed by its decay via $X\to l^- l^+$. The ALP can be either promptly decaying or long-lived. We perform Monte-Carlo simulations, recasting a prompt search at Belle for lepton-flavor-violating $\tau$ decays, and propose a displaced-vertex (DV) search. For both types of searches, we derive the Belle~II sensitivity reaches in both the product of branching fractions and the ALP coupling constants, as functions of the ALP mass and lifetime. The results show that the DV search exceeds the sensitivity reach of the prompt search to the relevant branching fractions by up to about a factor of 40 in the long decay length regime.

Neutron stars can shine a light on elusive lepton-flavor-violating dark matter
Flavor blocking keeps lepton-flavor-violating dark matter from thermalizing inside neutron stars, so p-wave annihilation stays efficient and heats the star to observable temperatures.

Same-sign dimuon probe of charged lepton flavor violation at electron-photon colliders
Electron–photon collisions are shown to probe axionlike-particle e–mu flavor-violating couplings via a same-sign dimuon signature, with projected sensitivity one to two orders below current bounds.
