## TL;DR

This study searches for signs of supersymmetry in proton-proton collision data at 13 TeV, focusing on events with photons, jets, and missing transverse momentum, but finds no significant deviations from the standard model, setting new mass exclusion limits.

## Contribution

First comprehensive search for supersymmetry with photon, jets, and missing momentum at 13 TeV, establishing new exclusion limits on gluino and top squark masses.

## Key findings

- No significant excess observed over standard model predictions.
- Gluino masses up to 2120 GeV are excluded.
- Top squark masses up to 1230 GeV are excluded.

## Abstract

A search for supersymmetry is presented based on events with at least one photon, jets, and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 35.9 fb$^{-1}$ and were recorded at the LHC with the CMS detector in 2016. The analysis characterizes signal-like events by categorizing the data into various signal regions based on the number of jets, the number of b-tagged jets, and the missing transverse momentum. No significant excess of events is observed with respect to the expectations from standard model processes. Limits are placed on the gluino and top squark pair production cross sections using several simplified models of supersymmetric particle production with gauge-mediated supersymmetry breaking. Depending on the model and the mass of the next-to-lightest supersymmetric particle, the production of gluinos with masses as large as 2120 GeV and the production of top squarks with masses as large as 1230 GeV are excluded at 95% confidence level.
