Search for the lepton-flavor-violating decays at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +447
We present the result of a search for the charged-lepton-flavor violating decays , where is a muon or an electron, using a data sampl…
Test of lepton flavor universality with measurements of and using semileptonic tagging at the Belle II experiment
Belle II Collaboration, I. Adachi, K. Adamczyk +450
We report measurements of the ratios of branching fractions ${\cal R}(D^{(*)+}) = \frac{{\cal B}(\overline{B}{}^0 \to D^{(*)+} \,Ï^- \, \overlineν_Ï)}{{\cal B}(\overline{B}{}^0…
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…
Search for Pcs(4459) and Pcs(4338) in Upsilon(1S,2S) inclusive decays at Belle
I. Adachi, L. Aggarwal, H. Ahmed +402
Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy collider, we search f…
