Angular analysis of $B \to K^{*} e^{+} e^{-}$ in the low- $q^{2}$ region with new electron identification at Belle

Belle Collaboration, D. Ferlewicz, P. Urquijo +167

We perform an angular analysis of the $B \to K^{*} e^{+} e^{-}$ decay for the dielectron mass squared, $q^{2}$ , range of $0.0008$ to $1.1200 GeV^{2} / c^{4}$ using the full Belle data se…

Evidence of $h_{b} (2P) \to I^¥ (1S) I^\cdot$ decay and search for $h_{b} (1P,2P) \to I^¥ (1S) I ¨ ^{0}$ with the Belle detector

Belle Collaboration, E. Kovalenko, I. Adachi +164

We report the first evidence for the $h_{b} (2P) \to I^¥ (1S) I^\cdot$ transition with a significance of $3.5$ standard deviations. The decay branching fraction is measured to…

Search for Two-Body $B$ Meson Decays to $I^^{0}$ and $I^c ◯_{c}^{(*) 0}$

Belle Collaboration, V. Savinov, I. Adachi +146

We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral $B$ mesons to $I^^{0}$ and $I^c ◯_{c}^{(*) 0}$ using 711~${\rm fb^…
