First measurements of absolute branching fractions of $Ξ_{c}^{0}$ at Belle

Belle Collaboration, Y. B. Li, C. P. Shen +158

We present the first measurements of absolute branching fractions of $Ξ_{c}^{0}$ decays into $Ξ^{-} π^{+}$ , $Λ K^{-} π^{+}$ , and $p K^{-} K^{-} π^{+}$ final states. The measurements are made using a…

Search for a light CP-odd Higgs boson and low-mass dark matter at the Belle experiment

Belle Collaboration, I. S. Seong, S. E. Vahsen +187

We report on the first Belle search for a light CP-odd Higgs boson, $A^{0}$ , that decays into low mass dark matter, $χ$ , in final states with a single photon and missing energy. We…
