Measurements of the branching fraction, isospin asymmetry, and lepton-universality ratio in $B \to J / ψ K$ decays at Belle II

Belle II Collaboration, F. Abudinén, I. Adachi +591

We report a study of $B \to J / ψ (ℓ^{+} ℓ^{-}) K$ decays, where $ℓ$ represents an electron or a muon, using $e^{+} e^{-}$ collisions at the $Υ (4 S)$ resonance. The data were col…

The JSNS $^{2}$ data acquisition system

J. S. Park, S. Ajimura, M. Botran +58

The JSNS $^{2}$ (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) experiment aims to search for neutrino oscillations over a 24 m short baseline at J-PARC. The JS…
