Probing the SM with Dijets at the LHC

TL;DR

This paper demonstrates how LHC dijet measurements can test the Standard Model at unprecedented levels, setting bounds on new physics such as four-quark interactions, extra gauge bosons, and top asymmetry explanations.

Contribution

It provides the most stringent bounds on four-quark interactions, compositeness scales, and constraints on new gauge bosons using LHC dijet data.

Findings

Stringent bounds on four-quark interactions

Limits on compositeness scale of quarks and gluons

Constraints on Z', W', G' bosons and top asymmetry models

Abstract

The LHC has started to explore the TeV energy regime, probing the SM beyond LEP and Tevatron. We show how the dijet measurements at the LHC are able to test certain sectors of the SM at an unprecedented level. We provide the best bounds on all possible four-quark interactions and translate them into limits on the compositeness scale of the quarks and gluons. We also provide constraints on extra gauge bosons, Z', W' and G', and on new interactions proposed to explain the present measurement of the forward-backward asymmetry of the top.
