The talk will present the most recent results obtained by the CMS collaboration on minimum bias processes and the so-called underlying event.

1. From Underlying Event Sensitive To Insensitive: Factorization and Resummation

Yiannis Makris

In this talk we will discuss the transverse energy spectrum for the Drell-Yan process. The transverse energy is measured within the central region defined by a (pseudo-) rapidity cutoff. Soft-collinear effective theory (SCET) is used to factorize the cross section and resum large logarithms of the rapidity cutoff and ratios of widely separated scales that appear in the fixed order result. We...

26. Fragmentation studies with the ATLAS detector

Abstract: Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation, as identified b-tagged jets provide a proxy for the quark daughters of the initial gluon. If available, we present a measurement of key differential distributions related to g→b bbar using data collected with the ATLAS detector at √s=13 TeV. Track jets are used to probe angular scales below...

58. Physics of small collision systems using UE observables

Antonio Ortiz Velasquez (Universidad Nacional Autonoma (MX))

12/12/2018, 10:00

In this work we study the underlying event (UE) activity as a function of the highest jet transverse momentum ($p_{\rm T}^{\rm jet}$) in terms of the number and summed $p_{\rm T}$ densities of charged particles in the azimuthal region transverse to the $p_{\rm T}^{\rm jet}$ direction. The UE activity considering charged particles within different $p_{\rm T}$ intervals in $pp$ collisions at...

27. Jet Substructure Measurements with the ATLAS Detector

Miguel Villaplana (Università degli Studi e INFN Milano (IT))

12/12/2018, 10:20

Abstract: Calculations of jet substructure observables which are accurate beyond leading-logarithmic accuracy have recently become available. Such observables are significant not only for probing a new regime of QCD at a hadron collider, but also for improving the understanding of jet substructure properties that are used in many studies at the Large Hadron Collider. In this talk, we discuss...
