Multiparton interactions with an x-dependent proton size

Corke, Richard LU and Sjöstrand, Torbjörn LU orcid (2011) In Journal of High Energy Physics
Abstract
Theoretical arguments, supported by other indirect evidence, suggest that the wave function of high-x partons should be narrower than that of low-x ones. In this article, we present a modification to the variable impact parameter framework of PYTHIA 8 to model this effect. In particular, a Gaussian hadronic matter profile is introduced, with a width dependent on the x value of the constituent being probed. Results are compared against the default single-and double-Gaussian profiles, as well as an intermediate overlap function.
