The photon content of the proton

Journal of High Energy Physics, 2017
The photon PDF of the proton is needed for precision comparisons of LHC cross sections with theoretical predictions. In a recent paper, we showed how the photon PDF could be determined in terms of the electromagnetic proton structure functions F 2 and F ...

The diffraction cone for exclusive vector meson production in deep inelastic scattering [PDF]

, 1997
We develop the color dipole gBFKL phenomenology of a diffraction cone for photo-and electroproduction γ*N−VN of heavy vector mesons (charmonium & bottomonium) at HERA and in fixed target experiments.

Pion-induced Drell-Yan processes within TMD factorization

Journal of High Energy Physics, 2019
We extract the pion transverse momentum dependent (TMD) parton distribu- tion by fitting the pion-induced Drell-Yan process within the framework of TMD factoriza- tion.

TMD fragmentation functions at N3LO

Journal of High Energy Physics, 2021
We compute the unpolarized quark and gluon transverse-momentum dependent fragmentation functions (TMDFFs) at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD.

Joint thrust and TMD resummation in electron-positron and electron-proton collisions

Journal of High Energy Physics, 2021
We present the framework for obtaining precise predictions for the transverse momentum of hadrons with respect to the thrust axis in e + e − collisions. This will enable a precise extraction of transverse momentum dependent (TMD) fragmentation functions ...

Inclusive prompt photon-jet correlations as a probe of gluon saturation in electron-nucleus scattering at small x

Journal of High Energy Physics, 2021
We compute the differential cross-section for inclusive prompt photon+quark production in deeply inelastic scattering of electrons off nuclei at small x (e + A DIS) in the framework of the Color Glass Condensate effective field theory.

J/ψ polarization in semi-inclusive DIS at low and high transverse momentum

Journal of High Energy Physics, 2022
We study the polar and azimuthal decay angular distributions of J/ψ mesons produced in semi-inclusive, deep-inelastic electron-proton scattering. For the description of the quarkonium formation mechanism, we adopt the framework of nonrelativistic QCD ...

Extraction of partonic transverse momentum distributions from semi-inclusive deep-inelastic scattering, Drell-Yan and Z-boson production

Journal of High Energy Physics, 2017
We present an extraction of unpolarized partonic transverse momentum distributions (TMDs) from a simultaneous fit of available data measured in semi-inclusive deep-inelastic scattering, Drell-Yan and Z boson production.

The production of the doubly charmed baryon in deeply inelastic ep scattering at the Large Hadron Electron Collider

Journal of High Energy Physics, 2020
In this paper, we carry out a detailed study on the production of the doubly charmed baryon in deeply inelastic ep scattering (DIS) for Q 2 ∈ [2, 100] GeV2, at the Large Hadron Electron Collider (LHeC) with E e = 60(140) GeV and E p = 7000 GeV.

Measuring Parton Densities in the Pomeron [PDF]

, 1994
We present a program to measure the parton densities in the pomeron using diffractive deep inelastic scattering and diffractive photoproduction, and to test the resulting parton densities by applying them to other processes such as the diffractive ...
