Proton structure fluctuations: from HERA to the LHC
arXiv:1706.05937
Abstract
We constrain the amount of event-by-event fluctuations of the proton by comparing with the HERA coherent and incoherent diffractive production data. We find that the HERA measurements prefer large geometric fluctuations. We then include the constrained fluctuating proton shapes in viscous hydrodynamical simulations of the proton-nucleus collisions at TeV, and find a good description of the mean transverse momentum and flow harmonics measured at the LHC.
