  1. 288. Probing transversity GPDs in diffractive electroproduction on the proton and deuteron at an electron-ion collider

    WG7: Future of DIS
    Parallel Session Talk

    A future electron-ion collider (EIC) with forward detectors would allow for measurements of coherent production of two vector mesons on proton and deuteron targets. In kinematics where the two vector mesons are separated by a large rapidity gap, one vector meson is produced at large transverse momenta and the other is transversily polarized, this process can probe the transversity generalized...

  2. 248. Determination of diffractive parton densities at the LHeC and the FCC-eh

    WG7: Future of DIS
    Parallel Session Talk

    The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An ERL will provide electrons to collide with the HL-LHC, HE-LHC and the FCC-hh proton and ion beams to achieve per nucleon centre-of-mass energies 1.3-3.5 (0.8-2.2) TeV and luminosities $\sim 10^{34(33)}$ cm$^{-2}$s$^{-1}$. These three configurations will enlarge the kinematic plane by more than one order of...

  3. 237. Measuring the Weizsäcker-Williams distribution of linearly polarized gluons at an electron-ion collider through dijet azimuthal asymmetries

    Parallel Session Talk

    The production of a hard dijet with small transverse momentum imbalance in semi-inclusive DIS probes the conventional and linearly polarized Weizsäcker-Williams (WW) transverse momentum dependent (TMD) gluon distributions. The latter, in particular, gives rise to an azimuthal dependence of the dijet cross section. In this talk I will discuss the feasibility of a measurement of these TMDs...

  4. 253. Sub-eikonal spin corrections and g1 structure function at low-x

    Parallel Session Talk

    Most of the progress in high-energy Quantum Chromodynamics has been obtained within the eikonal approximation and infinite Wilson-line operators. Evolution equations of Wilson lines with respect to the rapidity parameter encode the dynamics of the hadronic processes at high energy. However, even at high energy many interesting aspects of hadron dynamics are not accessible within the eikonal...

  5. 47. Collinearly improved impact-parameter dependent Balitsky-Kovchegov evolution

    Parallel Session Talk

    The Balitsky-Kovchegov equation has been successfully used to describe a wide range of
    processes in diffraction, saturation physics and many others. It has a wide use both in
    phenomenology and theory and its solution (the scattering amplitude) has received
    significant attention in the past years. However, the impact-parameter dependent solutions
    have been shown to exhibit so-called Coulomb...
