Electroweak gauge boson parton distribution functions [PDF]
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

Parton Distribution Functions in the CTEQ framework [PDF]
Dera Natung Government College Research Journal, 2020 Parton distribution functions (PDFs) are important to study the structure of the proton and hence the dynamics of quarks and gluons inside it. We study some of the PDFs from global CTEQ (Coordinated Theoretical-Experimental project on QCD) analysis in a ...

A model calculation of double parton distribution functions of the pion
European Physical Journal C: Particles and Fields, 2018 Two-parton correlations in the pion are investigated in terms of double parton distribution functions. A Poincaré covariant light-front framework has been adopted.

Nucleon quasi-parton distributions in the large Nc limit
Physics Letters B, 2020 In this letter, we investigate the nucleon quasi-parton distribution functions in the chiral quark soliton model. We derive a set of sum-rules depending on the velocity of the nucleon and on the Dirac matrix defining the distribution functions.

Semi-inclusive deeply inelastic electron nucleus scattering in the eN collinear frame
Nuclear Physics B, 2023 Our understanding of the parton-level structure in the nucleon comes predominantly from the electron deeply inelastic scattering measurements with very high precision. It deserves further study.

A data-based parametrization of parton distribution functions
European Physical Journal C: Particles and Fields, 2022 Since the first determination of a structure function many decades ago, all methodologies used to determine structure functions or parton distribution functions (PDFs) have employed a common prefactor as part of the parametrization.

Generalized parton distribution functions of $\rho$ meson
SciPost Physics Proceedings, 2020 We report our recent calculations for the generalized parton distribution functions of the $\rho$ meson with the help of a light-front constituent quark model. The electromagnetic form factors and structure functions of the system are given. Moreover,

Parton distribution functions in the context of parton showers [PDF]
, 2014 When the initial state evolution of a parton shower is organized according to the standard “backward evolution” prescription, ratios of parton distribution functions appear in the splitting probabilities.
