Full event interpretation at Belle II — •William Sutcliffe for the Belle II collaboration — University of Bonn, Bonn, Germany
The Belle II experiment is an e+ e− collider experiment in Japan, which was designed to record a large number of e+ e− collisions producing Υ(4S) → B B decays. A wide range of precision tests of the Standard Model and searches for new physics can be performed by studying the subsequent decays of the B mesons. In many cases, these decays will involve missing energy due to weakly interacting particles such as neutrinos, which escape the detector without interacting. Given the challenging nature of reconstructing decays with missing energy an essential technique, known as tag-side reconstruction, is employed in which one B meson is reconstructed in a large number of specific decay modes. This subsequently allows the kinematics and potentially the flavour of the remaining B meson to be constrained. In this talk, first results, which quantify the performance of the Belle II hadronic tag-side reconstruction algorithm, Full Event Interpretation (FEI), are presented using 5.15 fb−1 of early Belle II data. Ultimately the FEI will be an integral part of the physics program of Belle II allowing the measurement of several challenging final states such as b → s ν ν decays.
