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 $h = π^{\pm}$ , $…

Measurements of the mass difference $m (B^{0}) - m (B^{+})$ and the energy dependence of the cross-section ratio $σ (e^{+} e^{-} \to B^{0} B ˉ^{0}) / σ (e^{+} e^{-} \to B^{+} B^{-})$ at Belle and Belle II

Belle, Belle II Collaborations, : +396

Using data samples collected by the Belle and Belle II experiments at the $Υ (4 S)$ resonance with integrated luminosities of 571 fb $^{- 1}$ and 365 fb $^{- 1}$ , respectively, we measur…

First measurements of the branching fractions for the decay modes $Ξ_{c}^{0} \to Λ η$ and $Ξ_{c}^{0} \to Λ η^{'}$ and search for the decay $Ξ_{c}^{0} \to Λ π^{0}$ using Belle and Belle II data

Belle, Belle II Collaborations, : +321

Using data samples of 988.4 fb $^{- 1}$ and 427.9 fb $^{- 1}$ collected with the Belle and Belle II detectors, we present a study of the singly Cabibbo-suppressed decays $Ξ_c^{0} \to Λ…

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

Measurements of the mass difference m(B0)−m(B+) and the energy dependence of the cross-section ratio σ(e+e−→B0Bˉ0)/σ(e+e−→B+B−) at Belle and Belle II

First measurements of the branching fractions for the decay modes Ξc0​→Λη and Ξc0​→Λη′ and search for the decay Ξc0​→Λπ0 using Belle and Belle II data
