Search for lepton-flavor-violating $τ$ decays into a lepton and a vector meson using the full Belle data sample

Belle Collaboration, N. Tsuzuki, K. Inami, I. Adachi et autres

Charged-lepton-flavor-violation is predicted in several new physics scenarios. We update the analysis of $τ$ lepton decays into a light charged lepton ($\ell$ = $e^{\pm}$ or $μ^{\pm}$) and a vector meson ($V^0$ = $ρ^0$, $ϕ$, $ω$, $K^{\ast0}$, or $\overline{K}{}^{\ast0}$) using 980 fb$^{-1}$ of …

Search for the decay B+→K¯*0K*+ at Belle

Y. M. Goh, Y. Unno, B. G. Cheon, A. Abdesselam et autres

We report a search for the rare charmless decay ${B}^{+}\ensuremath{\rightarrow}{\overline{K}}^{*0}{K}^{*+}$ using a data sample of $772\ifmmode\times\else\texttimes\fi{}1{0}^{6}$ $B\overline{B}$ pairs collected at the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. No statistically significant signal is found and a 90% …
