Search for charmed baryons in the $Λ_{c}^{+} η$ system and measurement of the branching fractions of $Λ_{c} (2880)^{+}$ and $Λ_{c} (2940)^{+}$ decaying to $Λ_{c}^{+} η$ and $p D^{0}$ relative to $Σ_{c} (2455) π$

Belle Collaboration, S. X. Li, C. P. Shen +125

We search for excited charmed baryons in the $Λ_{c}^{+} η$ system using a data sample corresponding to an integrated luminosity of 980 $f b^{- 1}$ . The data were collected by the Bell…

Evidence of $h_{b} (2P) \to Υ (1S) η$ decay and search for $h_{b} (1P,2P) \to Υ (1S) π^{0}$ with the Belle detector

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

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

Search for Two-Body $B$ Meson Decays to $Λ^{0}$ and $Ω_{c}^{(*) 0}$

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 $Λ^{0}$ and $Ω_{c}^{(*) 0}$ using 711~${\rm fb^{-…

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…

Silicon Vertex Detector of the Belle II Experiment

S. Mondal, K. Adamczyk, L. Aggarwal +72

The silicon vertex detector (SVD) is installed at the heart of the Belle II experiment, taking data at the high-luminosity $B$ -Factory SuperKEKB since 2019. The detector has shown…

Search for the semileptonic decays $Ξ_{c}^{0} \to Ξ^{0} ℓ^{+} ℓ^{-}$ at Belle

Belle Collaboration, J. X. Cui, Y. B. Li +163

Using the full data sample of 980 $fb^{- 1}$ collected with the Belle detector at the KEKB asymmetric energy electron-positron collider, we report the results of the first…
