Analysis of B0 → ρ0 ρ0 decays at Belle II — •Justin Skorupa, Hans-Günther Moser, and Yingming Yang — Max-Planck-Institut für Physik, Garching, Deutschland
Measurements of the sides and angles of the unitary triangle associated to B-meson decays are a cornerstone of the Belle II physics program. Of all angles of the unitary triangle, the angle α/φ2 currently is the least precisely known.. The most precise determination of this angle comes from an analysis of isospin related B → ρ ρ decays. Of all B → ρ ρ modes, an improved measurement of B0 → ρ0 ρ0 is expected to have the strongest impact on the precision of α/φ2. In this talk, initial studies on the measurement of B0 → ρ0 ρ0 using Belle II data are presented.
