Observation of time-dependent $C P$ violation and measurement of the branching fraction of $B^{0} \to J / I ¨ I ¨ ^{0}$ decays

Belle II Collaboration, I. Adachi, L. Aggarwal +391

We present a measurement of the branching fraction and time-dependent charge-parity ( $C P$ ) decay-rate asymmetries in $B^{0} \to J / I ¨ I ¨ ^{0}$ decays. The data sample was collected with t…

Search for the baryon number and lepton number violating decays $I ¨ ^{-} \to I^ I ¨ ^{-}$ and $I ¨ ^{-} \to I^ˉ I ¨ ^{-}$ at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +371

We present a search for the baryon number $B$ and lepton number $L$ violating decays $I ¨ ^{-} \to I^ I ¨ ^{-}$ and $I ¨ ^{-} \to I^ˉ I ¨ ^{-}$ produced from the $e^+e^-\to Ï^+Ï…
