Hard Diffraction With Dynamic Gap Survival
(2016) In Journal of High Energy Physics 2016(2). p.1-38- Abstract
- We present a new framework for the modelling of hard diffraction in pp and (Formula presented.) collisions. It starts from the the approach pioneered by Ingelman and Schlein, wherein the single diffractive cross section is factorized into a Pomeron flux and a Pomeron PDF. To this it adds a dynamically calculated rapidity gap survival factor, derived from the modelling of multiparton interactions. This factor is not relevant for diffraction in ep collisions, giving non-universality between HERA and Tevatron diffractive event rates. The model has been implemented in Pythia 8 and provides a complete description of the hadronic state associated with any hard single diffractive process. Comparisons with (Formula presented.) and pp data reveal... (More)
