Title
Longitudinal momentum shifts, showering, and nonperturbative corrections in matched next-to-leading-order shower event generators
Author
Abstract
Comparisons of experimental data with theoretical predictions for collider processes containing hadronic jets rely on shower Monte Carlo event generators to include corrections to perturbative calculations from hadronization, parton showering, and multiple parton collisions. We examine current treatments of these corrections and propose alternative methods to take into account nonperturbative effects and parton showering in the context of next-to-leading-order event generators. We point out sizable parton-showering corrections to jet transverse energy spectra at high rapidity and discuss kinematic shifts in longitudinal momentum distributions from initial state showering in the case both of jet production and of heavy mass production at the Large Hadron Collider.
