Measurement of the $I^_{c}^{+}$ lifetime

Belle II Collaboration, F. AbudinÃ©n, L. Aggarwal +360

An absolute measurement of the $I^_{c}^{+}$ lifetime is reported using $I^_{c}^{+} \to p K^{-} I ¨ ^{+}$ decays in events reconstructed from data collected by the Belle II experiment at t…

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…

Measurement of the energy dependence of the $e^{+} e^{-} \to B B ˉ$ , $B B ˉ^{}$ , and $B^{} B ˉ^{*}$ cross sections at Belle~II

Belle II Collaboration, I. Adachi, L. Aggarwal +466

We report measurements of the $e^{+} e^{-} \to B B ˉ$ , $B B ˉ^{*}$ , and $B^{*} B ˉ^{*}$ cross sections at four energies, 10653, 10701, 10746 and 10805 MeV, using data collected b…

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…
