Search for Single and Pair-Production of Dijet Resonances with the CMS Detector

TL;DR

This paper reports on searches for new physics via dijet resonance signatures in proton-proton collisions at the LHC, setting limits on various models and excluding certain resonance masses.

Contribution

It presents the first exclusion limits for a coloron in paired dijet spectra and extends the mass range for string resonance exclusions.

Findings

No evidence for new dijet resonances was observed.

String resonances are excluded for masses between 1 and 4.7 TeV.

Colorons are excluded for masses between 250 and 740 GeV.

Abstract

Searches for new physics in the single and paired dijet mass spectrum are performed using data collected by the CMS experiment at the LHC at a collision energy of sqrt{s}=7 or sqrt{s}=8 TeV. No evidence for new physics is found and upper limits are set for various models. At 95% confidence level, a string resonance in the single dijet spectrum is excluded for masses between 1 and 4.7 TeV and, for the first time, a coloron in the paired dijet spectrum is excluded for masses between 250 and 740 GeV.
