Abstract

Searches for new physics beyond the Standard Model performed by the CMS experiment in final states with jets and leptons+jets are presented. The document focuses on a selection of recent results from searches for heavy dijet resonances, leptoquarks, and heavy majorana neutrinos using proton-proton collision data at both √s = 8 and 13 TeV. The novel CMS datascouting technique, used to probe the low-mass region in hadronic final states, is introduced and results from a Run1 analysis are shown. Two searches in the electrons+jets final states showing an excess of events in Run1 data are also discussed.

Highlights

  • Searches for new physics beyond the Standard Model performed by the CMS experiment [1] at the CERN LHC are presented in these conference proceedings

  • Results are obtained√using proton-proton collision data collected in Run1 (2012) at s = 8 TeV and Run2 (2015) at s = 13 TeV

  • Events used for the search are required to have ∆η j j = |η j1 − η j2| < 1.3 reducing significantly the QCD multijet background in t-channel with respect to the s-channel process of resonance production
