Illuminating the 1/x Moment of Parton Distribution Functions [PDF]
, 2007 The Weisberger relation, an exact statement of the parton model, elegantly relates a high-energy physics observable, the 1/x moment of parton distribution functions, to a nonperturbative low-energy observable: the dependence of the nucleon mass on the ...

New approach in the quantum statistical parton distribution
Physics Letters B, 2017 An attempt to find simple parton distribution functions (PDFs) based on quantum statistical approach is presented. The PDFs described by the statistical model have very interesting physical properties which help to understand the structure of partons ...

Exploring twist-4 chiral-even GPDs in the light-front quark-diquark model
Nuclear Physics BIn this work, we delve into the realm of quantum chromodynamics (QCD) by calculating twist-4 chiral-even generalized parton distributions (GPDs), within the context of the light-front quark-diquark model (LFQDM), focusing specifically on the intriguing ...

Gluon quasidistribution function at one loop
European Physical Journal C: Particles and Fields, 2018 We study the unpolarized gluon quasidistribution function in the nucleon at one loop level in the large momentum effective theory. For the quark quasidistribution, power law ultraviolet divergences arise in the cut-off scheme and an important observation

Charge Symmetry Breaking in Parton Distribution Functions from Lattice QCD [PDF]
, 2020 By determining the quark momentum fractions of the octet baryons from N f = 2 + 1 lattice simulations, we are able to predict the degree of charge symmetry violation in the parton distribution functions of the nucleon.

Generalized parton distributions of pion for non-zero skewness in AdS/QCD
Nuclear Physics B, 2018 We study the generalized parton distributions (GPDs) of pion for non-zero skewness by considering the leading |qq¯〉 Fock state component. Inspired from AdS/QCD light-front wave functions, we calculate the pion GPDs.

Flavor asymmetry of light sea quarks in proton: a light-front spectator model
European Physical Journal C: Particles and FieldsWe formulate a light-front spectator model for the proton that incorporates the presence of light sea quarks. In this particular model, the sea quarks are seen as active partons, whereas the remaining components of the proton are treated as spectators ...

The twist-three distribution eq(x,k⊥) in a light-front model
Physics Letters B, 2019 We discuss the twist-three, unpolarized, chiral-odd, transverse momentum dependent parton distribution (TMD) eq(x,k⊥) within a light-front model. We review a model-independent decomposition of this TMD, which follows from the QCD equations of motion and ...
