Measurement of the branching fractions and $C P$ asymmetries of $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +582

We determine the branching fractions $B$ and $C P$ asymmetries $A_{CP}$ of the decays $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ . The result…

Search for a dark photon and an invisible dark Higgs boson in $μ^{+} μ^{-}$ and missing energy final states with the Belle II experiment

Belle II Collaboration, F. Abudinén, I. Adachi +357

The dark photon $A^{'}$ and the dark Higgs boson $h^{'}$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^\pri…
