Measurement of $C P$ violation in $B^{0} \to K_{S}^{0} I ¨ ^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +399

We report a measurement of the $C P$ -violating parameters $A$ and $S$ in $B^{0} \to K_{S}^{0} I ¨ ^{0}$ decays at Belle II using a sample of $387 \times 1 0^{6}$ $B B ˉ$ events reco…

The Imaging Time-of-Propagation Detector at Belle II

Hulya Atmacan, Matt Belhorn, Yinghui Guan +92

We report on the construction, operation, and performance of the Time-of-Propagation detector with imaging used for the Belle II experiment running at the Super-KEKB $e^{+} e^{-}$ colli…

Search for a long-lived spin-0 mediator in $b \to s$ transitions at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +411

Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles $S$ in $B$ -meson decays mediated by a $b \to s$ quark transiti…
