Session: WG1
Different distributions of charged-particles and leading charged-particle produced in proton-proton collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV are measured in the pseudorapidity range $|\eta| < 2.4$ for charged-particles with a transverse momentum $p_T~>~0.5$ GeV. Measurements are presented for four event categories. The first two categories correspond to inclusive and inelastic e ... More

Recent measurements, performed with the CMS and TOTEM experiments, of the elastic and inelastic cross section are presented and compared. The inelastic cross section at 13 TeV is measured with CMS in two fiducial regions using information from forward calorimetry, and finally extrapolated to the full inelastic phase space.

Session: WG1
The modelling of Minimum Bias (MB) is a crucial ingredient to learn about the description of soft QCD processes. It has also a significant relevance for the simulation of the environment at the LHC with many concurrent pp interactions (“pileup”). The ATLAS collaboration has provided new measurements of the inclusive charged particle multiplicity and its dependence on transverse momentum ... More

The modelling of the Underlying Event (UE) is a crucial component in the complete description of both soft and hard QCD processes at hadron colliders. The ATLAS collaboration presents new results on the number and transversemomentum sum of charged particles as a function of the leading high pT track in events taken at a center of mass energy of 13 TeV. These results are presented in regions t ... More

We present results on the measurement of the underlying event at 13 TeV using leading tracks, jets, and Drell-Yan processes. In addition measurements of forward-backward particle correlations and the rapidity gap fraction are presented. Finally results on charged particle multiplicity and transverse momenta distributions are shown.

Session: WG1
By measuring the substructure of a jet, one can assign it a quark or gluon tag. In this talk, we confront the challenges faced when going beyond this leading-order understanding, using both parton shower generators and first-principles calculations to assess the impact of higher-order perturbative and nonperturbative physics. Working in the idealized context of electron-positron collisions,where ... More

Session: WG1
Underlying-event activity is defined as the soft particle production in proton+proton collisions which is not directly related to the final fragmentation of hard-scattered partons. Underlying-event measurements therefore provide a tool to study non-factorizable and non-perturbative phenomena. Systematic measurements of the relationship between the underlying event and jet processes provide a cruci ... More
