Searches for new physics with leptons and jets at CMS

TL;DR

This paper reports on CMS searches for various hypothetical particles predicted by beyond Standard Model theories, using 2011-2012 data, finding no evidence but setting new limits on these models' parameters.

Contribution

First comprehensive search for multiple new physics models with leptons and jets at CMS using 7 and 8 TeV data, establishing new exclusion limits.

Findings

No evidence of new particles was observed.

Set new limits on parameters of various beyond Standard Model theories.

Analyzed data from 2011 and 2012 at 7 and 8 TeV.

Abstract

A variety of models of physics beyond the standard model predict new particles that decay to leptons, jets, or both together. These models include axigluons, colorons, diquarks, excited quarks, heavy long-lived charged particles, leptoquarks, Randall-Sundrum gravitons, string resonances, and new vector bosons (right-handed W and Z'). Using the data collected in 2011 and 2012 at center-of-mass energies of 7 and 8 TeV, the CMS collaboration has performed searches for these new particles in channels with leptons and jets. The results of these searches will be presented. No evidence of new physics has been observed, and these results set new limits on the parameters of these models.
