Inclusive search for supersymmetry using razor variables in pp collisions at ffiffi s p = 13 TeV
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an integrated luminosity of 2.3 fb−1 collected with the CMS experiment at a center-o...

| Summary: | An inclusive search for supersymmetry using razor variables is performed in events with four or more
jets and no more than one lepton. The results are based on a sample of proton-proton collisions
corresponding to an integrated luminosity of 2.3 fb−1 collected with the CMS experiment at a center-ofmass energy of ffiffi
s p ¼ 13 TeV. No significant excess over the background prediction is observed in data,
and 95% confidence level exclusion limits are placed on the masses of new heavy particles in a variety of
simplified models. Assuming that pair-produced gluinos decay only via three-body processes involving
third-generation quarks plus a neutralino, and that the neutralino is the lightest supersymmetric particle
with a mass of 200 GeV, gluino masses below 1.6 TeV are excluded for any branching fractions for the
individual gluino decay modes. For some specific decay mode scenarios, gluino masses up to 1.65 TeV are
excluded. For decays to first- and second-generation quarks and a neutralino with a mass of 200 GeV,
gluinos with masses up to 1.4 TeV are excluded. Pair production of top squarks decaying to a top quark and
a neutralino with a mass of 100 GeV is excluded for top squark masses up to 750 GeV. |
