Belle II results on charmless hadronic B-decays and prospects — •Justin Skorupa, Thibaud Humair, Hans-Günther Moser, Markus Reif, and Benedikt Wach — Max Planck Institute for Physics
The Belle II experiment at the SuperKEKB e+ e- accelerator in Tsukuba, Japan, aims to constrain the parameters of the Cabibbo-Kobayashi-Maskawa matrix by measuring the size of the sides and angles of the unitary triangle associated to B-meson decays. Possible non-closure of the triangle would provide a hint for physics beyond the Standard Model. Belle II will significantly improve the accuracy of the determination of the angle φ2 of the unitary triangle due to the large yield of expected charmless hadronic B-meson decays. Measurements of branching ratios of several charmless hadronic B-meson decays using 190 fb−1 of Belle II data are presented.
