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.…

Searches for charged-lepton-flavor violation in $χ_{b J} (1 P)$ decays

Belle, Belle II Collaborations, : +425

We report the first searches for charged-lepton-flavor violation in decays of $χ_{b J} (1 P)$ ( $J = 0, 1,$ and $2$ ) to a pair of charged leptons using 158 million $Υ (2 S)$ decays collect…

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…

Measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +416

We perform a measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays using a dataset of approximately $772 \times 1 0^{6}$ and $521 \times 10…

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…

Kink Finder at Belle II

Denis Bodrov, Xinping Xu, Dmitrii Gavrilov +27

We present a track-finding algorithm for the Belle II experiment that specifically targets so-called kinks: signatures of charged particles decaying or scattering in-flight in the…
