Charged-lepton-flavor-violation is predicted in several new physics scenarios. We update the analysis of $\tau$ lepton decays into a light charged ($\ell$ = $e^{\pm}$ or $\mu^{\pm}$) and vector meson ($V^0$ $\rho^0$, $\phi$, $\omega$, $K^{\ast0}$, $\overline{K}{}^{\ast0}$) using 980 fb$^{-1}$ data collected with Belle detector at KEKB collider. No significant excess such signal events observed, thus 90% credibility level upper limits are set on $\tau \rightarrow \ell V^0$ branching fractions...

We search for the tree-diagram dominated process B+→pn¯π0, using a data sample of 772×106BB¯ pairs collected at ϒ(4S) resonance with Belle detector KEKB asymmetric-energy e+e− collider. This is first decay mode including an antineutron. No significant signal observed and 90% credible upper limit on branching fraction set 6.3×10−6.Received 17 December 2022Accepted 12 September 2023DOI:https://doi.org/10.1103/PhysRevD.108.112007Published by American Physical Society under terms Creative...
