Search for a light Higgs boson in single-photon decays of $Υ (1 S)$ using $Υ (2 S) \to π^{+} π^{-} Υ (1 S)$ tagging method

Belle Collaboration, S. Jia, C. P. Shen +210

We search for a light Higgs boson ( $A^{0}$ ) decaying into a $τ^{+} τ^{-}$ or $μ^{+} μ^{-}$ pair in the radiative decays of $Υ (1 S)$ . The production of $Υ (1 S)$ mesons is tagged by $Υ(2S)\to π^+…

Measurements of the branching fractions of $Ξ_{c}^{0} \to Λ K_{S}^{0}$ , $Ξ_{c}^{0} \to Σ^{0} K_{S}^{0}$ , and $Ξ_{c}^{0} \to Σ^{+} K^{-}$ decays at Belle

Belle collaboration, Y. Li, J. X. Cui +213

Using the entire data sample of $980 fb^{- 1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we present measurements of the branching f…

First test of Lepton Flavor Universality in the charmed baryon decays $Ω_{c}^{0} \to Ω^{-} ℓ^{+} ν_{ℓ}$ using data of the Belle experiment

Belle Collaboration, Y. B. Li, C. P. Shen +203

We present the first observation of the $Ω_{c}^{0} \to Ω^{-} μ^{+} ν_{μ}$ decay and present measurements of the branching fraction ratios of the $Ω_{c}^{0} \to Ω^{-} \ell^{+} ν_{\ell…

Measurement of the branching fraction and $C P$ asymmetry for $B \to D ˉ^{0} π$ decays

Belle Collaboration, T. Bloomfield, M. E. Sevior +212

We measure the branching fractions and $C P$ asymmetries for the decays $B^{0} \to D ˉ^{0} π^{0}$ and $B^{+} \to D ˉ^{0} π^{+}$ , using a data sample of $772 \times 1 0^{6}$ $B\bar…

Search for $B^{0}$ meson decays into $Λ$ and missing energy with a hadronic tagging method at Belle

Belle Collaboration, C. Hadjivasiliou, B. G. Fulsom +166

We present a search for the decays of $B^{0}$ mesons into a final state containing a $Λ$ baryon and missing energy. These results are obtained from a $711 fb^{- 1}$ data sample…

Combined analysis of Belle and Belle II data to determine the CKM angle $ϕ_{3}$ using $B^{+} \to D (K_{S}^{0} h^{-} h^{+}) h^{+}$ decays

Belle, Belle II Collaborations, : +319

We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $ϕ_{3}$ (also known as~ $γ$ ) using a model-independent Dalitz plot analysis of \linebreak $B^+\t…
