Underlying Event Measurements at CMS

TL;DR

This paper presents measurements of underlying event activity in proton-proton collisions at CMS, comparing results across different energies to understand energy dependence.

Contribution

First CMS measurements of underlying event activity across multiple energies, providing data for tuning theoretical models.

Findings

Underlying event activity varies with collision energy.

CMS data helps refine models of proton-proton interactions.

Results are consistent with previous experiments at similar energies.

Abstract

Measurements of Underlying Event activity using proton-proton collision data collected by the CMS detector will be presented. To check the energy dependence of the underlying event activity, results are compared with previous measurements from different experiments at different centre-of-mass energies.
