Search for lepton-flavor-violating tau decays to $\ellα$ at Belle Open
We report a search for the lepton-flavor-violating decays $τ^{\pm}\to\ell^{\pm}α$~($\ell=e,μ$), where $α$ is an undetected spin-0 particle, such as an axion-like particle using $736\times10^{6}$ tau lepton pairs collected by the Belle dete…

We report evidence for the charged charmed-strange baryon $\Xi_{c}(2930)$ with a signal significance of 3.9$\sigma$. The charged $\Xi_{c}(2930)$ is found in its decay to $K_{S}^{0} \Lambda_{c}$ in the substructure of $B^{0} \to K^{0}_{S} \…
