A search for the flavor-changing neutral-current decay B+→K+νν¯ is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data sample corresponds to an integrated luminosity of 63 fb−1 collected at the ϒ(4S) resonance and a sample of 9 fb−1 collected at an energy 60 MeV below the resonance. Because the measurable decay signature involves only a single charged kaon, a novel measurement approach is used that exploits not only the properties of the B+→K+νν¯ decay, but also the inclusive properties of the other B meson in the ϒ(4S)→BB¯ event, to suppress the background from other B meson decays and light-quark pair production. This inclusive tagging approach offers a higher signal efficiency co...
