Description
We present searches for the charged lepton-flavor-violating decays $\Upsilon(1S) \to \ell \ell'$ and radiative charged lepton-flavour-violating decays $\Upsilon(1S) \to \gamma \ell \ell'$ [where $\ell =e,\mu$ and $\ell'=e,\mu,\tau$] using the 158 million Υ(2S) sample collected by the Belle detector at the KEKB collider. These searches use $\Upsilon(1S)$ mesons produced in $\pi^+\pi^-\Upsilon(1S)$ transitions. We also present Belle searches for the charged lepton-flavor-violating decays $B_s \to \ell \tau$ and $\Upsilon(2S) \to \ell \tau$.
