Contribution

It provides a comprehensive overview of current experimental approaches and challenges in modeling soft inelastic interactions at the LHC.

Findings

Uncertainties in soft pp inelastic interaction modeling are significant.

Comparison of trigger strategies at ATLAS and CMS reveals different approaches.

Ongoing analyses aim to improve understanding of underlying event dynamics.

Abstract

An overview of minimum bias and underlying event studies at the LHC with the ATLAS and CMS detectors is presented. Current uncertainties in the modeling of soft pp inelastic interactions at the LHC energy scale are discussed. Triggers used to select inelastic interactions at ATLAS and CMS are described and compared. A summary of some of the ongoing minimum bias and underlying event analyses by the ATLAS and CMS collaborations is given.
