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…

Search for $B^{+} \to μ^{+} ν_{μ}$ and $B^{+} \to μ^{+} N$ with inclusive tagging

M. T. Prim, F. U. Bernlochner, P. Goldenzweig +191

We report the result for a search for the leptonic decay of $B^{+} \to μ^{+} ν_{μ}$ using the full Belle data set of 711 fb $^{- 1}$ of integrated luminosity at the $Υ (4 S)$ resonance.…

Measurement of $R (D)$ and $R (D^{*})$ with a semileptonic tagging method

The Belle Collaboration, G. Caria, P. Urquijo +188

The experimental results on the ratios of branching fractions $R (D) = B (B ˉ \to D τ^{-} ν ˉ_{τ}) / B (B ˉ \to D ℓ^{-} ν ˉ_{ℓ})$ and $\mathcal{R}(D^…

Measurement of the integrated luminosity of the Phase 2 data of the Belle II experiment

Belle II Collaboration, F. Abudinén, I. Adachi +420

From April to July 2018, a data sample at the peak energy of the $Υ (4 S)$ resonance was collected with the Belle~II detector at the SuperKEKB electron-positron collider. This is 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…

Implementation of GENFIT2 as an experiment independent track-fitting framework

Tadeas Bilka, Nils Braun, Thomas Hauth +10

The GENFIT toolkit, initially developed at the Technische Universitaet Muenchen, has been extended and modified to be more general and user-friendly. The new GENFIT, called GENFIT2…

Global Decay Chain Vertex Fitting at B-Factories

J. -F. Krohn, P. Urquijo, F. Abudinén +17

We present a particle vertex fitting method designed for B factories. The presented method uses a Kalman Filter to solve a least squares estimate to globally fit decay chains, as o…
