Abstract |
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an R-parity-violating coupling into a lepton and a W, Z, or Higgs boson. This search targets the Higgs boson decay channel of the charginos and neutralinos, using events with three or more b-tagged jets and one or two electrons or muons. The analyzed data corresponds to an integrated luminosity of 140 fb(-1) and 56 fb(-1) of proton-proton collision data produced by the Large Hadron Collider at center-of-mass energies of root s = 13 TeV and root s = 13.6 TeV, respectively, collected by the ATLAS experiment between 2015 and 2023. The data are found to be consistent with predictions from the Standard Model. The results are interpreted as limits at 95% confidence level on model-independent cross sections for processes beyond the Standard Model. Limits are also set on the production of charginos and neutralinos for a minimal supersymmetric Standard Model with an additional B – L gauge symmetry that is spontaneously broken. Charginos and neutralinos with masses between 150 GeV and 1100 GeV are excluded at 95% confidence level for a scenario in which they decay via Higgs bosons, assuming equal decay branching fractions to each lepton flavor. Additional limits on chargino and neutralino production are derived for flavor-specific decay scenarios where the charginos decay into a single lepton flavor. |
