Search for new physics in B → D^(*) τ ν decays — Thomas Kuhr, Thomas Lück, and •Liang Qiao — Ludwig-Maximilians-Universität, München

The decays B → D^(*) τ ν are one of the few cases where a significant deviation from the standard model prediction was observed in the experiment. Therefore it is essential to study these decays in as much detail as possible. The expected huge dataset and the sophisticated analysis tools at Belle II will open new analysis techniques to investigate possible violations of lepton universality using Monte Carlo simulations as well as the reconstruction of B mesons. Ideas of an inclusive reconstruction of the second B meson in Y(4S) → BB events will be presented.
