Description

Abstract: A search for the flavor-changing neutral current decay B + → K + ν ν̄ is performed with an electron-positron collision data sample corresponding to 63 fb-1 collected at the Υ (4S) resonance by the Belle II experiment. A measurement method is developed, which exploits topological properties of the decay that differ from both generic bottom-meson decays and light-quark pair-production. This inclusive tagging approach has the benefit of a higher signal efficiency compared to previous searches for this rare decay. It represents the first B-physics result from the Belle-II experiment.
