Search for the Decay $B_{s}^{0} \to η^{'} η$

Belle Collaboration, A. Abdesselam, I. Adachi +459

In the Standard Model (SM) charmless hadronic decays $B_{s}^{0} \to η^{'} η$ proceed via tree-level $b \to u$ and penguin $b \to s$ transitions. Penguin transitions are sensit…

Charmless $B$ decay reconstruction in 2019 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +533

We report on the reconstruction of various charmless $B$ decays from electron-positron collisions at the energy corresponding to the $Υ (4 S)$ resonance collected with the Belle II d…

Evidence for the decay $B^{0} \to η η$

A. Abdesselam, I. Adachi, K. Adamczyk +447

We report a search for $B^{0} \to η η$ with a data sample corresponding to an integrated luminosity of $698 fb^{- 1}$ containing $753 \times 1 0^{6}$ $B B ˉ$ pairs collected…
