The impact parameter dependence of color charge correlators in the proton is obtained from the light front formalism in light cone gauge. We include NLO corrections due to the |qqqg⟩|qqqg⟩ Fock state via light-cone perturbation theory. Near the center of the proton, the bb-dependence of the correlations is very different from a "transverse profile function". The resulting tt-dependence of exclusive J/ΨJ/Ψ photoproduction transitions from exponential to power law at |t|≈1|t|≈1 GeV22. This prediction could be tested at upcoming DIS facilities or in nucleus-proton ultraperipheral collisions (UPCs).

Confronting the impact parameter dependent JIMWLK evolution with HERA data
Mäntysaari, Heikki; Schenke, Björn (American Physical Society, 2018)The small-x evolution of protons is determined from numerical solutions of the JIMWLK equations, starting from an initial condition at moderate x for a finite size proton. The resulting dipole amplitude is used to calculate ... -
Impact parameter dependent JIMWLK evolution meets HERA data
Mäntysaari, H.; Schenke, B. (Sissa Medialab srl, 2019)We calculate the small-x evolution of protons with finite size by solving numerically the JIMWLK evolution equation. The initial condition is constrained by the HERA measurements of charm reduced cross section and of ... -
Multiplicity dependence of (multi-)strange hadron production in proton-proton collisions at √s = 13 TeV
ALICE Collaboration (Springer, 2020)The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity (|y|<0.5) are measured in proton-proton collisions at s√ = 13 TeV as a function of the charged particle multiplicity, using ... -
Observation of a multiplicity dependence in the pT-differential charm baryon-to-meson ratios in proton–proton collisions at √s = 13 TeV
ALICE Collaboration (Elsevier BV, 2022)The production of prompt D0, Ds+, and Λc+ hadrons, and their ratios, Ds+/D0 and Λc+/D0, are measured in proton–proton collisions at s=13 TeV at midrapidity (|y|<0.5) with the ALICE detector at the LHC. The measurements are ... -
Study of flavor dependence of the baryon-to-meson ratio in proton-proton collisions at √ s = 13 TeV
ALICE Collaboration (American Physical Society (APS), 2023)The production cross sections of D0 and Λ+c hadrons originating from beauty-hadron decays (i.e., nonprompt) were measured for the first time at midrapidity (|y|<0.5) by the ALICE Collaboration in proton-proton collisions ...
