Search for new phenomena with large jet multiplicities and missing transverse momentum using large-radius jets and flavour-tagging at ATLAS in 13 TeV pp collisions Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration, / Beyond Standard Model Hadron-Hadron scattering (experiments) Supersymmetry A search is presented for particles that decay producing a large jet multiplicityand invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on the number of b-tagged jets and the scalar sum of masses of large-radius jets. Having explored the full ATLAS 2015-2016 dataset of LHC proton-proton collisions at √s = 13TeV, which corresponds to 36.1 fb-1 of integrated luminosity, no evidence is found for physics beyond the Standard Model. The results are interpreted in the context of simplified models inspired by R-parity-conserving and R-parity-violating supersymmetry, where gluinos are pair-produced. More generic models within the phenomenological minimal supersymmetric Standard Model are also considered. 2024-10-11T10:07:00Z 2024-10-11T10:07:00Z 2017-12-06 journal article The ATLAS collaboration., Aaboud, M., Aad, G. et al.
