Title: | A search for pair-produced resonances in four-jet final states at √s=13 TeV with the ATLAS detector | Authors: | Santos, S. P. Amor dos Carvalho, J. Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2018 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 78 | Issue: | 3 | Abstract: | A search for massive coloured resonances which are pair-produced and decay into two jets is presented. The analysis uses 36.7 fb−1 of √ s = 13 TeV pp collision data recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the background prediction is observed. Results are interpreted in a SUSY simplified model where the lightest supersymmetric particle is the top squark, ˜t, which decays promptly into two quarks through Rparity- violating couplings. Top squarks with masses in the range 100 GeV < m˜t < 410 GeV are excluded at 95% confidence level. If the decay is into a b-quark and a light quark, a dedicated selection requiring two b-tags is used to exclude masses in the ranges 100 GeV < m˜t < 470 GeV and 480 GeV < m˜t < 610 GeV. Additional limits are set on the pair-production of massive colour-octet resonances. | URI: | https://hdl.handle.net/10316/107571 | DOI: | 10.1140/epjc/s10052-018-5693-4 | Rights: | openAccess |
