Measurement of branching fractions and direct $C P$ asymmetries for $B \to K π$ and $B \to π π$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +435

We report measurements of the branching fractions and direct $CP$ asymmetries of the decays $B^{0} \to K^{+} π^{-}$ , $B^{+} \to K^{+} π^{0}$ , $B^{+} \to K^{0} π^{+}$ , and $B^{0} \to K^{0} π^{0}$ , and…

Study of the muon decay-in-flight in the $τ^{-} \to μ^{-} ν ˉ_{μ} ν_{τ}$ decay to measure the Michel parameter $ξ^{'}$

Belle Collaboration, D. Bodrov, P. Pakhlov +192

We present the first measurement of the Michel parameter $ξ^{'}$ in the $τ^{-} \to μ^{-} ν ˉ_{μ} ν_{τ}$ decay using the full data sample of $988 fb^{- 1}$ collected by the Belle de…
