New analysis for Nucleon Form Factors from GPDs
Fatemeh Arbabifar, Nader Morshedian, Shahin Atashbar Tehrani
Generalized Parton Distributions (GPDs) provide a comprehensive framework for describing the three-dimensional structure of the nucleon. Extracting GPDs from experimental data requ…
Nucleon Form Factors from GPDs
Leila Ghasemzadeh, Pegah Sartipi YarAahmadi, Fatemeh Arbabifar +2
In this study, we introduce a novel ansatz for Generalized Parton Distributions (GPDs), named GSAMA24. This ansatz aims to provide a more accurate and comprehensive description of…
AAK24: Global QCD analysis on polarized parton distribution in the presence of asymmetry measurements
Fatemeh Arbabifar, Shahin Atashbar Tehrani, Hamzeh Khanpour
This article introduces {\tt AAK24}, a Next-to-Leading Order (NLO) QCD analysis of polarized data from both polarized Deep Inelastic Scattering (DIS) and Semi-Inclusive Deep Inelas…
QCD analysis of structure functions in deep-inelastic scattering: Mellin transform by Gegenbauer polynomial up to NLO approximation
Fatemeh Arbabifar, Nader Morshedian, Leila Ghasemzadeh +1
This paper provides a thorough examination of the structure functions in deep-inelastic scattering through a comprehensive QCD analysis. Our approach harnesses sophisticated…
The Jacobi Polynomials QCD analysis for the polarized structure function
S. Atashbar Tehrani, Ali N. Khorramian
We present the results of our QCD analysis for polarized quark distribution and structure function . We use very recently experimental data to parameterize our model.…
The NNLO non-singlet QCD analysis of parton distributions based on Bernstein polynomials
Ali N. Khorramian, S. Atashbar Tehrani
A non-singlet QCD analysis of the structure function up to NNLO is performed based on the Bernstein polynomials approach. We use recently calculated NNLO anomalous dimension…
