Contribution

It presents new soft-QCD measurements in the forward region at LHCb, focusing on energy flow, multiplicity, and hadron ratios to refine theoretical models.

Findings

Energy flow measurements in different event classes

Charged particle multiplicity data for underlying event modeling

Prompt hadron and baryon ratios for hadronisation and baryon transport models

Abstract

The LHCb detector with its unique pseudorapidity coverage allows to perform soft-QCD measurements in the kinematic forward region where QCD models have large uncertainties. Selected analyses related to soft-Diffraction will be summarised in these proceedings. Energy flow and charged particle multiplicity have been measured separately in different event classes. They give input for modelling the underlying event in pp collisions. Prompt hadron ratios are important for hadronisation models, while the $\bar p/p$ ratio is a good observable to test models of baryon number transport.
