TL;DR

This paper discusses measurements at the LHC involving Mueller Navelet and jet gap jets to test BFKL dynamics, and explores anomalous $WW\gamma\gamma$ couplings to probe beyond Standard Model physics.

Contribution

It provides a NLL calculation for jet processes and demonstrates the potential to significantly improve constraints on anomalous couplings using forward detectors.

Findings

NLL calculation of jet cross sections aligns with Tevatron data.

Forward detector measurements can improve sensitivity to anomalous couplings by four orders of magnitude.

Proposes new tests for BFKL dynamics and beyond Standard Model physics at the LHC.

Abstract

We describe two different important measurements to be performed at the LHC. The Mueller Navelet jet and jet gap jet cross section represent a test of BFKL dynamics and we perform a NLL calculation of these processes and compare it with recent Tevatron measurements. The study of the $WW\gamma \gamma$ couplings at the LHC using the forward detectors proposed in the ATLAS Forward Physics project as an example allows to probe higgsless and extradimension models via anomalous quartic couplings since the reach is improved by four orders of magnitude with respect to the LEP results.
