Search for supersymmetry using vector boson fusion signatures and missing transverse momentum in pp collisions at SQUARE ROOTs = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

This paper presents a search for supersymmetric particles in models with highlycompressed mass spectra, in events consistent with being produced through vector bosonfusion. The search uses 140 fb-1 of proton-proton collision data at SQUARE ROOTs = 13TeV collected bythe ATLAS experiment at the Large Hadron Collider. Events containing at least two jetswith a large gap in pseudorapidity, large missing transverse momentum, and no reconstructedleptons are selected. A boosted decision tree is used to separate events consistent with theproduction of supersymmetric particles from those due to Standard Model backgrounds.The data are found to be consistent with Standard Model predictions. The results areinterpreted using simplified models of R-parity-conserving supersymmetry in which thelightest supersymmetric partner is a bino-like neutralino with a mass similar to that of thelightest chargino and second-to-lightest neutralino, both of which are wino-like. Lower limitsat 95% confidence level on the masses of next-to-lightest supersymmetric partners in thissimplified model are established between 117 and 120 GeV when the lightest supersymmetricpartners are within 1 GeV in mass.
