Renormalons and power corrections in pseudo- and quasi-GPDs [PDF]
High-order behavior of the perturbative expansion for short-distance observables in QCD is intimately related to the contributions of small momenta in the corresponding Feynman diagrams and this correspondence provides one with a useful tool to ...

Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Hadron tomography studies by generalized parton distributions and distribution amplitudes
EPJ Web of Conferences, 2017 We discuss hadron-tomography studies for the nucleon and exotic hadrons by high-energy hadron reactions. First, the constituent-counting rule is explained for determining internal quark configurations of exotic-hadron candidates by scaling properties of ...

Sensitivity of Double Deeply Virtual Compton Scattering observables to GPDs
International audienceGeneralized Parton Distributions (GPDs) are multidimensonal structure functions that encode the information about the internal structure of hadrons.

ParticlesWe investigate the off-shell generalized parton distributions (GPDs) and transverse momentum dependent parton distributions (TMDs) of kaons within the framework of the Nambu–Jona-Lasinio model, employing proper time regularization.

European Physical Journal C: Particles and FieldsWe present a systematic study demonstrating the impact of lattice QCD data on the extraction of generalised parton distributions (GPDs). For this purpose, we use a previously developed modelling of GPDs based on machine learning techniques fulfilling the

Basic properties of GPDs and modelling of the latter
, 2019 International audienceWe present here a new method based on the Radon transform to model Generalised Parton Distributions (GPDs). It allows to fulfil all theoretical constraints applying on GPDs, especially polynomiality and positivity at the same time ...

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 ...

Chiral-even twist-3 GPDs for the proton in a spectator diquark model [PDF]
We investigate the chiral-even twist-3 generalized parton distributions (GPDs) of valence quarks in the proton at nonzero skewness $ξ$, using a spectator model with scalar and axial-vector diquarks. We consider the exponential form factor for the nucleon-
