Type: статьи в журналах
Date: 2021
Description:
We study the gluon parton densities [parton distribution functions (PDFs), transverse momentum distributions (TMDs), generalized parton distributions (GPDs)] and form factors in soft-wall AdS/QCD. We

Description:
We present an improved study of the electromagnetic form factors of the nucleon and of the Roper-nucleon transition using an extended version of the effective action of soft-wall AdS/QCD. We include n

Description:
We use different light-front wave functions (two inspired by the AdS/QCD formalism), together with a model of the nucleon in terms of meson–baryon fluctuations to calculate the nonperturbative (intrin

Description:
Continuing our analysis of parton distributions in the nucleon, we extend our light-front quark model in order to obtain both the helicity-independent and the helicity-dependent parton distributions,

Description:
We study the exclusive production of scalar S=0++ and tensor T=2++ mesons through single-photon annihilation e+e−→γ∗→γS(T). Using QCD compositeness of the involved hadrons considered as quark-antiquar

Description:
We study a scenario allowing a solution of the strong charge parity problem via the Peccei-Quinn mechanism, implemented in gravity with torsion. In this framework there appears a torsion-related pseud

Description:
We present a high-quality description of the deuteron electromagnetic form factors in a soft-wall anti-de Sitter/quantum chromodynamics approach. We first propose an effective action describing the dy

Description:
Using global fits of valence u and d quark parton distributions and data on quark and nucleon form factors in the Euclidean region, we derive a light-front quark model for the nucleon structure consis

Description:
We derive the lowest-order qq valence light-front wave function for the pion with Lz = 0 and |Lz| = 1, which reproduces its valence parton distribution and the electromagnetic form factor consistent w
