Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ with 2016 data

A search for supersymmetry is performed with proton-proton collision data recorded by the CMS experiment with a center-of-mass energy of $13~\mathrm{TeV}$ and an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. Data containing a single lepton are sorted into several exclusive search regions based on the number of jets and $b$-tagged jets, the scalar sum of the jet transverse momenta, and the scalar sum of the missing transverse momentum and the transverse momentum of the lepton. The observed number of events are consistent with the background expectation and the results are interpreted with two simplified supersymmetric models of gluino pair production. In the first model, each gluino decays via a three-body process to top quarks and a neutralino, which is associated with the observed missing transverse momentum in the event. Gluinos with masses up to $1.8~\mathrm{TeV}$ are excluded for neutralino masses below $800~\mathrm{GeV}$. In the second model, each gluino decays via a three-body process to two light quarks and a chargino, which subsequently decays to a $W$ boson and a neutralino. The mass of the chargino is taken to be midway between the gluino and neutralino masses. In this model, gluinos with masses below $1.9~\mathrm{TeV}$ are excluded for neutralino masses below $300~\mathrm{GeV}$.
