Název v původním jazyce

Search for pair production of higgsinos in final states with at least three b-tagged jets in √s=13 TeV pp collisions using the ATLAS detector

Popis výsledku v původním jazyce

A search for pair production of the supersymmetric partners of the Higgs boson (higgsinos H~) in gauge-mediated scenarios is reported. Each higgsino is assumed to decay to a Higgs boson and a gravitino. Two complementary analyses, targeting high- and low-mass signals, are performed to maximize sensitivity. The two analyses utilize LHC pp collision data at a center-of-mass energy √s=13 TeV, the former with an integrated luminosity of 36.1 fb−1 and the latter with 24.3 fb−1, collected with the ATLAS detector in 2015 and 2016. The search is performed in events containing missing transverse momentum and several energetic jets, at least three of which must be identified as b-quark jets. No significant excess is found above the predicted background. Limits on the cross-section are set as a function of the mass of the H~ in simplified models assuming production via mass-degenerate higgsinos decaying to a Higgs boson and a gravitino.n
