Search for an invisibly decaying $Z^{'}$ boson at Belle II in $e^{+} e^{-} \to μ^{+} μ^{-} (e^{\pm} μ^{\mp})$ plus missing energy final states

Belle II Collaboration, I. Adachi, P. Ahlburg +358

Theories beyond the standard model often predict the existence of an additional neutral boson, the $Z^{'}$ . Using data collected by the Belle II experiment during 2018 at the…

Test of lepton flavor universality and search for lepton flavor violation in $B \to K ℓℓ$ decays

S. Choudhury, S. Sandilya, K. Trabelsi +220

We present measurements of the branching fractions for the decays $B \to K μ^{+} μ^{-}$ and $B \to K e^{+} e^{-}$ , and their ratio ( $R_{K}$ ), using a data sample of 711 $f b^{- 1}$ that…

Test of lepton-flavor universality in $B \to K^{*} ℓ^{+} ℓ^{-}$ decays at Belle

Belle Collaboration, S. Wehle, I. Adachi +179

We present a measurement of $R_{K^{*}}$ , the branching fraction ratio $B (B \to K^{*} μ^{+} μ^{-})$ / $B (B \to K^{*} e^{+} e^{-})$ , for both charged and neutral $B$ meso…
