Studying the underlying event in Drell-Yan and high transverse momentum jet production at the Tevatron

We study the underlying event in proton-antiproton collisions by examining the behavior of charged particles produced in association with a large transverse momentum jet (~2.2  fb[superscript -1]) or with a Drell-Yan lepton pair (~2.7  fb[superscript -1]) in the Z-boson mass region [70<M(pair)<...

Description
Summary:We study the underlying event in proton-antiproton collisions by examining the behavior of charged particles produced in association with a large transverse momentum jet (~2.2  fb[superscript -1]) or with a Drell-Yan lepton pair (~2.7  fb[superscript -1]) in the Z-boson mass region [70<M(pair)<110  GeV/c[superscript 2]] as measured by CDF at 1.96 TeV center-of-mass energy. We use the direction of the lepton pair or the leading jet in each event to define regions of η[eta]-ϕ[phi] space that are sensitive to the modeling of the underlying event. The data are corrected to the particle level to remove detector effects and are then compared with several QCD Monte Carlo models.
