Measurements of the forward energy flow and forward jet production with CMS

TL;DR

This paper reports measurements of forward energy flow and jet production at CMS, comparing results with various Monte Carlo models to improve understanding of the underlying event in high-energy collisions.

Contribution

It provides the first measurements of inclusive forward jet cross section and central-forward jet correlations at CMS, enhancing modeling of forward physics.

Findings

Forward energy flow measurements agree with some MC models.

Inclusive forward jet cross section measured for the first time at CMS.

Results help refine MC models of the underlying event.

Abstract

We present measurements of the forward (3 < |eta| < 5) energy flow in minimum bias events and in events with either hard jets or W and Z bosons produced at central rapidities together with first measurements of the inclusive forward jet cross section and central forward jet correlations. Results are compared to MC models with different parameter tunes for the description of the underlying event.
