Recent data analysis to revisit the spin structure function of the nucleon in Laplace space

Considering a fixed-flavor number scheme and based on Laplace transformation, we perform leading-order and next-to-leading-order QCD analyses that include world data on polarized structure functions g1 and g2. During our analysis, taking the DGLAP evolution equations, we employ the Jacobi polynomials expansion technique. In our recent analysis we utilize the recent available data and consequently include more data than what we did in our previous analysis. We obtain good agreements between our results for the polarized parton densities and nucleon structure functions with all available experimental data and some common parametrization models.

Automated summary

Based on Laplace transformation and a fixed-flavor number scheme, we perform QCD analyses on polarized structure functions g1 and g2, including world data at leading-order and next-to-leading-order. By employing the Jacobi polynomials expansion technique and taking the DGLAP evolution equations, our recent analysis incorporates more data than our previous analysis and achieves good agreements with experimental data and parametrization models for polarized parton densities and nucleon structure functions.
