  1. 43. Schwinger based QCD formulation's derivation of elastic pp scattering
    Dr Peter Tsang (Brown University)

    Elastic Scattering and Total Cross Section

    Using previously described functional techniques for some non–perturbative, gauge invariant, renormalized QCD processes, a simplified version of the amplitudes — in which forms akin to Pomerons naturally appear — provides fits to ISR and LHC–TOTEM pp elastic scattering data. Those amplitudes rely on a specific function φ(b) which describes the fluctuations of the transverse position of quarks...

  2. 7. Results on Total and Elastic Cross Sections in Proton--Proton Collisions at $\sqrt{s} = 200$ GeV Obtained with the STAR Detector at RHIC.

    Elastic Scattering and Total Cross Section

    Bogdan Pawlik for the STAR Collaboration
    We report the first results on differential, total and elastic cross sections in proton-proton collisions at the Relativistic Heavy Ion Collider (RHIC) at $\sqrt{s}=200$ GeV. The data were obtained with the Roman Pot Detector subsystem of the STAR experiment. The data used for this analysis cover the four-momentum transfer squared ($t$) range $ 0.045...

  3. 22. Recent Elastic and Total Cross-Section Measurements by TOTEM
    Mario Deile (CERN)
    25/06/2019, 12:00
    Elastic Scattering and Total Cross Section

    The TOTEM experiment at the interaction point 5 of the LHC has measured the total, elastic and inelastic proton-proton cross sections in a centre-of-mass energy range from 2.76 to 13 TeV, mostly in dedicated fills with special beam optics.

    Most recently, TOTEM has performed a series of detailed measurements at $\sqrt{s}$ = 13 TeV. The total, elastic and inelastic proton-proton cross-sections...

  4. 19. Pomeron and Odderon: J/psi and eta_c electroproduction
    Tomasz Stebel (Institute of Nuclear Physics PAN)
    25/06/2019, 14:00
    Recent theoretical developments

    I will discuss exclusive J/psi and eta_c production in electron-proton collisions, mediated in the lowest order QCD by 2- and 3-gluon exchanges. In the recently developed model, we relate the amplitudes for those processes to the correlators of the quark current in the light-cone wave function of the proton. We obtain new estimates of eta_c cross-section at the energy W~10 GeV.

  5. 20. Size and Shape of Hadrons: From Pion Cloud to Pomeron/Odderon, and AdS/CFT
    Chung-I Tan (Brown University)
    25/06/2019, 14:30
    Elastic Scattering and Total Cross Section

    Proton-proton differential and total cross sections provide information on the energy dependence of proton shape and size. This will be discussed both from a phenomenological and theoretical perspectives. This will include the role of pion cloud, (e.g., Jenkowsky, Szanyi and Tan, hep-ph:1710.10594), new phenomenology based on AdS/CFT, (e.g., Watanabe, et al., hep-ph:1901.09564), and the...

  6. 48. Odderon, proton structure and hollowness from the model-independent Levy imaging of elastic hadron-hadron collisions

  7. 13. Measurements of the total cross section and the rho parameter using ATLAS
    ATLAS Collaboration
    Elastic Scattering and Total Cross Section

    A measurement of the ratio of the real to imaginary elastic scattering amplitude at zero momentum transfer (the rho parameter), and the total proton-proton scattering cross section are presented at √s=8 TeV. The measurement is made using the differential elastic cross section as a function of the Mandelstam momentum transfer variable, which is reconstructed using the ALFA forward spectrometer...
