Underlying event characteristics and their dependence on jet size of charged-particle jet events in pp collisions at √(s) = 7 TeV with the ATLAS detector

Abstract

Distributions sensitive to the underlying event are studied in events containing one or more charged-particle jets produced in pp collisions at √s=7  TeV with the ATLAS detector at the Large Hadron Collider (LHC). These measurements reflect 800  μb^(-1) of data taken during 2010. Jets are reconstructed using the anti-kt algorithm with radius parameter R varying between 0.2 and 1.0. Distributions of the charged-particle multiplicity, the scalar sum of the transverse momentum of charged particles, and the average charged-particle p_T are measured as functions of p_T^(jet) in regions transverse to and opposite the leading jet for 4  GeV
