    QUARK AND LEPTON FLAVOR PHYSICS
    Oral Presentation

    The Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider has been collecting the world’s highest-intensity collisions at the $\Upsilon$(4S) since 2019. A data set comparable in size to that of predecessor experiments, Belle, and collected with the new detector, enables unique or world-leading results. Examples include indirect searches for non-standard-model...

  3. 112. Luminosity and inelastic cross section determination for hadronic collisions with ALICE at the LHC

    STRONG INTERACTIONS HADRON PHYSICS
    Oral Presentation

    Cross section measurements are key to the ALICE physics program and require precise luminosity determination. In ALICE, the luminosity determination relies on visible cross sections measured in dedicated calibration experiments, the van der Meer scans. For the LHC Run 2 data samples, ALICE measured the luminosity with an uncertainty better than 2% for pp collisions and 3% for Pb-Pb collisions....

  4. 94. Beta decay of proton induced by high-power laser field
    Mohamed OUHAMMOU (Recherche Laboratory in Physics and Engineering Sciences, Team of Modern and Applied Physics, FPBM, USMS, Morocco)
    STRONG INTERACTIONS HADRON PHYSICS
    Oral Presentation

    In this work, we investigate the decay of the proton into neutron, positron and electron neutrino in the presence of an external electromagnetic field with circular polarization. Different physical quantities related to this decay process, such as proton’s decay rate and its lifetime, are calculated based on the S-matrix approach. The proton and positron are treated as Dirac-Volkov states,...

  5. 145. Observation of new structure in the J/ψJ/ψ mass spectrum in proton-proton collisions at √s = 13 TeV
    Xining Wang (Tsinghua University)
    STRONG INTERACTIONS HADRON PHYSICS
    Oral Presentation

    A search is reported for near-threshold structures in the J/ψJ/ψ invariant mass spectrum produced in proton-proton collisions at √s = 13 TeV from data collected by the CMS experiment, corresponding to an integrated luminosity of 135 fb−1. A new structure is observed with a significance above 5 standard deviations at a mass of 6552 ± 10 (stat) ± 12 (syst) MeV. Another structure with even higher...
