Search for the $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decay

Belle, Belle II Collaborations, : +432

We present the first search for $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decays. We look for signal decays in $B^{0} B ˉ^{0}$ events produced in asymmetric-energy electron-positron collisions.…

First measurement of the masses of the $I^¥_{1} (1 D)$ and $I^¥_{3} (1 D)$ states and the energy dependence of the cross sections for $e^{+} e^{-} \to I^¥_{J} (1 D) I^\cdot$ and $e^{+} e^{-} \to I^¥_{J} (1 D) I ¨ ^{+} I ¨ ^{-}$

Belle, Belle II Collaborations, : +398

We study the processes $e^{+} e^{-} \to I^¥_{J} (1 D) I^\cdot$ and $e^{+} e^{-} \to I^¥_{J} (1 D) I ¨ ^{+} I ¨ ^{-}$ at center-of-mass energies $s$ =(10.73 -- 11.02) GeV using a $142.5 fb^{- 1}$ data sampl…

Study of $B^{+} \to I^¼^{+} I^½_{I^} ¼$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay $B^{+} \to I^¼^{+} I^½_{I^} ¼$ . This work presents the first $B^{+} \to I^¼^{+} I^½_{I^} ¼$ result using Belle~II data, an updated Be…

Study of $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ (h = I ¨ , K, p)$ via initial-state radiation at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +417

Using a data sample of 427.9 fb $^{- 1}$ collected by the Belle~II detector at or near the $I^¥ (4 S)$ and $I^¥ (10753)$ resonances, the cross sections for $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ $ $(h=Ï/K…

Search for $I^^{0} p$ , $I^c ◯^{-} p$ , and $I^c ◯^{-} n$ dibaryons in $I^¥ (1 S)$ and $I^¥ (2 S)$ decays at Belle

Belle, Belle II Collaborations, : +367

We search for $I^^{0} p$ , $I^c ◯^{-} p$ , and $I^c ◯^{-} n$ dibaryon states in $I^¥ (1 S)$ and $I^¥ (2 S)$ decays, probing mass regions near the corresponding baryon-pair thresholds. Multistrange baryon…

Search for the lepton-flavor-violating $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{\mp}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +447

We present the result of a search for the charged-lepton-flavor violating decays $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{-}$ , where $ℓ$ is a muon or an electron, using a data sampl…
