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…

$R (3780)$ Resonance Interpreted as the $1^{3} D_{1}$ -Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^{+} e^{-} \to$ Hadrons

M. Ablikim, M. N. Achasov, P. Adlarson +606

We report the precise measurements of the cross section of $e^{+} e^{-} \to$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study…
