Title:Underlying-event Activity in Proton+Proton Collisions at
sqrt(s_NN) = 200GeV with the STAR Detector at RHIC
sqrt(s_NN) = 200GeV with the STAR Detector at RHIC
Speaker: Li Yi (Yale)
Abstract: 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 are
crucial for a complete description of both soft and hard QCD processes
at hadron colliders and for Monte Carlo modeling. In this talk, we
will report the progress of underlying-event measurements in
proton+proton collisions at RHIC by STAR and its comparison with Monte
Carlo tuning. The comparison between RHIC and LHC energy
underlying-event activities will also be discussed.
