# Search for supersymmetry in pp collisions at sqrt(s) = 13 TeV in the single-lepton final state using the sum of masses of large-radius jets

## TL;DR

This paper reports a search for supersymmetric particles in proton-proton collisions at 13 TeV using the CMS detector, finding no excess over standard model predictions and setting exclusion limits on gluino masses up to 1.9 TeV.

## Contribution

It introduces a new analysis method using the sum of large-radius jet masses to search for supersymmetry in single-lepton final states.

## Key findings

- No significant excess observed over standard model backgrounds.
- Gluino masses up to 1.9 TeV are excluded at 95% confidence level.
- The analysis constrains supersymmetric models involving gluino decays to top squarks.

## Abstract

Results are reported from a search for supersymmetric particles in proton-proton collisions in the final state with a single lepton; multiple jets, including at least one b-tagged jet; and large missing transverse momentum. The search uses a sample of proton-proton collision data at sqrt(s) = 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 inverse femtobarns. The observed event yields in the signal regions are consistent with those expected from standard model backgrounds. The results are interpreted in the context of simplified models of supersymmetry involving gluino pair production, with gluino decay into either on- or off-mass-shell top squarks. Assuming that the top squarks decay into a top quark plus a stable, weakly interacting neutralino, scenarios with gluino masses up to about 1.9 TeV are excluded at 95% confidence level for neutralino masses up to about 1 TeV.
