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.

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.

Semi-Exclusive Pion Production in Deep-Inelastic Scattering [PDF]
Phys.Lett. B347 (1995) 413-418, 1994 We calculate azimuthal asymmetries and the Callan-Gross $R$-ratio for semi-exclusive pion production in deep inelastic scattering taking into account higher twist effects. Our results are qualitatively different from the QCD-improved parton model predictions for semi-inclusive deep inelastic scattering.

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.

Electroweak gauge boson parton distribution functions
Journal of High Energy Physics, 2018 Transverse and longitudinal electroweak gauge boson parton distribution functions (PDFs) are computed in terms of deep-inelastic scattering structure functions, following the recently developed method to determine the photon PDF. The calculation provides

Operator product expansion of the non-local gluon condensate
Journal of High Energy Physics, 2021 We consider the short-distance expansion of the product of two gluon field strength tensors connected by a straight-line-ordered Wilson line. The vacuum expectation value of this nonlocal operator is a common object in studies of the QCD vacuum structure,

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]
EPJ Web of Conferences, 2022 Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...

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 ...

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.

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.
