Search for the lepton flavour violating decays $B^{+} \to K^{+} τ^\pm \ell^\mp$ ($\ell = e, μ$) at Belle

Belle Collaboration, S. Watanuki, G. de Marino, Karim Trabelsi et autres

We present a search for the lepton-flavour-violating decays $B^+ \to K^+ τ^\pm \ell^\mp$, with $\ell = (e, μ)$, using the full data sample of $772 \times 10^6$ $B\overline{B}$ pairs recorded by the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We …

Search for $B^{0} \to \tau^\pm \ell^\mp$ ($\ell=e,\mu$ ) with a hadronic tagging method at Belle

Belle II Collaboration, H. Atmacan, A. J. Schwartz, K. Kinoshita et autres

We present a search for the lepton-flavor-violating decays $B^{0} \to \tau^\pm \ell^\mp$, where $\ell=(e,\,\mu)$, using the full data sample of $772 \times 10^6$ $B \overline{B}$ pairs recorded by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We use events in which …
