Event Geometry and Anisotropic Flow in Proton-Proton Collisions
Abstract: We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. We then examine how this asymmetric probability density function compares to geometries without intrinsic anisotropy and data from the CMS and ALICE. This is achieved by simulations based in these geometries in a hydrodynamical toy model and in PYTHIA.
