Strong Interaction and Hadron Physics: Strong Interaction and Hadron Physics

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...
Production of muons from heavy-flavour hadron decays in pp collisions at √s = 13 TeV with the ALICE detector

Heavy quarks (charm and beauty) are produced in early stages of the hadronic collision via hard-parton scatterings. In ALICE,...
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....
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,...
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...
