Search for top squarks in final states with two top quarks and several light-flavor jets in proton-proton collisions at s=13 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, J. W. Andrejkovic et autres

Many new physics models, including versions of supersymmetry characterized by $R$-parity violation (RPV), compressed mass spectra, long decay chains, or additional hidden sectors, predict the production of events with top quarks, low missing transverse momentum, and many additional quarks or gluons. The …
