Study of $B^{+} \to μ^{+} ν_{μ}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay $B^{+} \to μ^{+} ν_{μ}$ . This work presents the first $B^{+} \to μ^{+} ν_{μ}$ result using Belle~II data, an updated Belle me…

A search for feebly-interacting particles in $B$ decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle $X_{inv}$ , produced in $B^{0} \to D ˉ^{0} X_{inv}$ and $B^{\pm} \to h X_{inv}$ decays, where $h = π^{\pm}$ , $…

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…

Measurement of Angular Coefficients of $B ˉ \to D^{*} ℓ ν ˉ_{ℓ}$ : Implications for $∣ V_{c b} ∣$ and Tests of Lepton Flavor Universality

Belle Collaboration, M. T. Prim, F. Bernlochner +158

We measure the complete set of angular coefficients $J_{i}$ for exclusive $B ˉ \to D^{*} ℓ ν ˉ_{ℓ}$ decays ( $ℓ = e, μ$ ). Our analysis uses the full $711 fb^{- 1}$ …

Search for baryon and lepton number violating decays $D \to p ℓ$

Belle Collaboration, S. Maity, R. Garg +159

We search for the baryon and lepton number violating charm decays, $D \to p ℓ$ , where $D$ is either a $D^{0}$ or a $D^{0}$ and $ℓ$ is a muon or an electron, usi…
