Title:Constraints for proton structure fluctuations from exclusive scattering

Authors:H. Mäntysaari, B. Schenke
View PDF
Abstract:We constrain the average density profile of the proton and the amount of event-by-event fluctuations by simultaneously calculating the coherent and incoherent exclusive diffractive vector meson production cross section in deep inelastic scattering. Working within the Color Glass Condensate picture, we find that the gluonic density of the proton must have large geometric fluctuations in order to describe the experimentally measured large incoherent cross section.
