Searches for physics beyond the standard model with the MT2 variable in hadronic final states with and without disappearing tracks in proton-proton collisions at s=13Te

Albert M. Sirunyan, +2285 more

- 03 Jan 2020

- European Physical Journal C

TL;DR: In this paper, two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance, based on a sample of proton-proton collisions at a center-of-mass energy of $13,\text {Te}\text {V} $, collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 137$
