CMS search plans and sensitivity to new physics with dijets

TL;DR

This paper discusses CMS's plans to use dijet events at the LHC to search for new physics phenomena such as contact interactions and dijet resonances, leveraging early data to extend beyond previous collider limits.

Contribution

It proposes a strategy for early LHC data analysis focusing on dijet events to detect new physics beyond the standard model.

Findings

Inclusive jet cross section sensitive to contact interactions

Dijet mass distribution can reveal new resonances

Comparing pseudorapidity regions enhances sensitivity

Abstract

CMS will use dijets to search for physics beyond the standard model during early LHC running. The inclusive jet cross section as a function of jet transverse momentum, with 10 inverse picobarns of integrated luminosity, is sensitive to contact interactions beyond the reach of the Tevatron. The dijet mass distribution will be used to search for dijet resonances coming from new particles, for example an excited quark. Additional sensitivity to the existence of contact interactions or dijet resonances can be obtained by comparing dijet rates in two distinct pseudorapidity regions.
