Description

The Belle II experiment is an e+e- collider experiment in Japan, which
begins its main physics run in early 2019. The clean environment of e+e-
collisions together with the unique event topology of Belle II, in which
an Υ(4S) particle is produced and subsequently decays to a pair of B
mesons, allows a wide range of physics measurements to be performed
which are difficult or impossible at hadron colliders. A critical
technique for many of these measurements is tag-side B meson
reconstruction, in which one B meson in the event is reconstructed. The
Full Event Interpretation is an algorithm which reconstructs tag-side B
mesons at Belle II. The algorithm trains multivariate classifiers to
classify O(100) unique decay channels, which allows it in turn to
reconstruct O(10000) decay chains. This talk presents the algorithm and
its performance relative to previous tag-side B meson reconstruction
algorithms.
