Title: Ballistic protons in incoherent exclusive vector meson production as a measure of rare parton fluctuations at an electron-ion collider

Abstract

We argue that the proton multiplicities measured in Roman pot detectors at an electron ion collider can be used to determine centrality classes in incoherent diffractive scattering. Incoherent diffraction probes the fluctuations in the interaction strengths of multi-parton Fock states in the nuclear wavefunctions. In particular, the saturation scale that characterizes this multi-parton dynamics is significantly larger in central events relative to minimum bias events. As an application, we examine the centrality dependence of incoherent diffractive vector meson production. We identify an observable which is simultaneously very sensitive to centrality triggered parton fluctuations and insensitive to details of the model.

Long-range azimuthal correlations in proton–proton and proton–nucleus collisions from the incoherent scattering of partons

Journal Article Ma, Guo -Liang ; Bzdak, Adam - Physics Letters. B

In this study, we show that the incoherent elastic scattering of partons, as present in a multi-phase transport model (AMPT), with a modest parton–parton cross-section of σ = 1.5 – 3 mb, naturally explains the long-range two-particle azimuthal correlation as observed in proton–proton and proton–nucleus collisions at the Large Hadron Collider.

We report on a study of diffractive dijet production in p̄p collisions at s√=1.96 TeV using the CDF II detector at the Fermilab Tevatron p̄p collider. A data sample from 310 pb⁻¹ of integrated luminosity collected by triggering on a high transverse energy jet, EjetT, in coincidence with a recoil antiproton detected in a Roman pot spectrometer is used to measure the ratio of single-diffractive to inclusive-dijet event rates as a function of x^p̄ of the interacting parton in the antiproton, the Bjorken-x, x^p̄_Bj, and a Q²≈(E^jet_T)² in the ranges 10⁻³^p̄_Bj<10⁻¹ and 10²<10⁴ GeV², respectively.

Evidence of strong proton shape fluctuations from incoherent diffraction

Journal Article Mantysaari, H. ; Schenke, B. - Physical Review Letters

We show within the saturation framework that measurements of exclusive vector meson production at high energy provide evidence for strong geometric fluctuations of the proton. In comparison, the effect of saturation scale and color charge fluctuations is weak. This knowledge will allow detailed future measurements of the incoherent cross section to tightly constrain the fluctuating geometry of the proton as a function of the parton momentum fraction x.

Novel High Transverse Momentum Phenomena in Hadronic and Nuclear Collisions

Conference Brodsky, Stanley J ; /SLAC

I discuss a number of novel phenomenological features of QCD in high transverse momentum reactions. The presence of direct higher-twist processes, where a proton is produced directly in the hard subprocess, can explain the 'baryon anomaly' - the large proton-to-pion ratio seen at RHIC in high centrality heavy ion collisions. Direct hadronic processes can also account for the deviation from leading-twist PQCD scaling at fixed x{sub T} = 2 p{sub T}/{radical}s. I suggest that the 'ridge' --the same-side long-range rapidity correlation observed at RHIC in high centrality heavy ion collisions is due to the imprint of semihard DGLAP gluon radiationmore »« less
