New measurements of decays into single charm final states
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1147
Using proton-proton collision data corresponding to an integrated luminosity of collected by the LHCb experiment, searches are performed for mesons d…
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…
Coherent photoproduction of and excited vector mesons in ultraperipheral PbPb collisions
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132
The invariant-mass distribution for the coherent photoproduction of dipions in ultraperipheral PbPb collisions is measured using data, corresponding to an integrated luminosity of…
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 to cross-section ratio as a function of centrality in PbPb collisions at = 5.02 TeV
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1133
The dissociation of quarkonium states with different binding energies produced in heavy-ion collisions is a powerful probe for investigating the formation and properties of the qua…
