Exclusive diffractive processes at HERA within the dipole picture
13 Pith papers cite this work. Polarity classification is still indexing.
abstract
We present a simultaneous analysis, within an impact parameter dependent saturated dipole model, of exclusive diffractive vector meson (J/psi, phi and rho) production, deeply virtual Compton scattering and the total gamma* p cross section data measured at HERA. Various cross sections measured as a function of the kinematic variables Q^2, W and t are well described, with little sensitivity to the details of the vector meson wave functions. We determine the properties of the gluon density in the proton in both longitudinal and transverse dimensions, including the impact parameter dependent saturation scale. The overall success of the description indicates universality of the emerging gluon distribution and proton shape.

Physics-informed neural networks extract a model-independent color dipole amplitude from inclusive HERA data that predicts exclusive J/ψ photoproduction cross-sections without parameter retuning.
Unpolarized GPDs and GTMDs at small x with non-zero skewness are expressed via the dipole amplitude N and odderon O with modified rapidity Y = ln min{1/|x|, 1/|ξ|}.
Extension of KoMPoST to (3+1)D non-boost-invariant pre-equilibrium dynamics via kinetic theory response functions, chained into a full McDIPPER+KoMPoST-3D+CLVisc+SMASH simulation chain to study sensitivity of longitudinal flow to hydrodynamic start time.
Replacing the rapidity argument of the dipole amplitude with ln min{1/|x|, 1/|ξ|} and refining initial conditions for non-linear evolution can eliminate two R-factors in small-x shockwave calculations.
Comparison of SMASH and McDipper initial condition models shows agreement in longitudinal deposition at lower energies but substantial differences in energy and baryon deposition at higher center-of-mass energies.
Model predictions for coherent and incoherent rho and J/psi photoproduction cross sections in O-O and Ne-Ne ultraperipheral collisions, comparing Woods-Saxon and cluster-based nuclear shapes.
Color dipole calculations of the ratio of exclusive vector meson to inclusive jet/hadron photoproduction cross sections in UPC pA and AA collisions at LHC Run 4, including the double ratio R_UPC proposed for saturation studies.
A suppression factor R_G=0.85 is tuned to F2 and rho photoproduction data and used to predict observables for rho(2S), omega, and phi states via holographic wave functions in the dipole picture.
A review summarizing experimental evidence, theoretical models of nuclear shadowing, model-agnostic nuclear PDF extractions, and prospects for LHC and EIC studies.
The EIC Yellow Report specifies the science goals, required detector capabilities, and technology concepts needed to realize a high-luminosity electron-ion collider program.
