Search for a Dark Higgs Boson Produced in Association with Inelastic Dark Matter at the Belle II Experiment

Belle II Collaboration, I. Adachi, L. Aggarwal +437

Inelastic dark matter models that have two dark matter particles and a massive dark photon can reproduce the observed relic dark matter density without violating cosmological limit…

Measurement of the $D^{0} \to K^{-} I ¨ ^{+} e^{+} e^{-}$ branching fraction and search for $D^{0} \to I ¨ ^{+} I ¨ ^{-} e^{+} e^{-}$ and $D^{0} \to K^{+} K^{-} e^{+} e^{-}$ decays at Belle

Belle, Belle II Collaborations, : +481

We present a study of the rare charm meson decays $D^{0} \to K^{+} K^{-} e^{+} e^{-}$ , $I ¨ ^{+} I ¨ ^{-} e^{+} e^{-}$ , and $K^{-} I ¨ ^{+} e^{+} e^{-}$ using a 942 fb $^{- 1}$ data se…

Search for $C P$ violation in $D_{(s)}^{+} \to K_{S}^{0} K^{-} I ¨ ^{+} I ¨ ^{+}$ decays using triple and quadruple products

Belle, Belle II Collaborations, : +366

We perform the first search for $C P$ violation in $D_{(s)}^{+} \to K_{S}^{0} K^{-} I ¨ ^{+} I ¨ ^{+}$ decays. We use a combined data set from the Belle and Belle II experiments, which…
