NNLO Determination of Polarized Parton Distribution Functions with Higher-Twist and Target-Mass Corrections
Javad Shahrzad, Elliot Leader, Ali Khorramian
We present a next-to-next-to-leading order (NNLO) QCD analysis of polarized parton distribution functions (PDFs) based on the world data set of inclusive polarized deep-inelastic s…
The Role of Higher Twist in Determining Polarized Parton Densities from DIS data
E. Leader, A. V. Sidorov, D. B. Stamenov
Different methods to extract the polarized parton densities from the world polarized DIS data are considered. The higher twist corrections to the spin dependent proton…
Fragmentation functions and their role in determining the polarized parton densities
S. Kretzer, E. Leader, E. Christova
We extract the pion fragmentation functions and their uncertainties from a judicious choice of e+e- and semi-inclusive DIS data. These are used to study the error propagation in th…
A New Evaluation of Polarized Parton Densities in the Nucleon
E. Leader, A. V. Sidorov, D. B. Stamenov
We present a new leading and next-to-leading QCD analysis of the world data on inclusive polarized deep inelastic scattering. A new set of polarized parton densities is extracted f…
Fragmentation functions from semi-inclusive DIS pion production and implications for the polarized parton densities
E. Christova, S. Kretzer, E. Leader
By combining recent HERMES data on semi-inclusive DIS -production with the singlet fragmentation function , which is well determined from data, we are ab…
Polarized Parton Densities in the Nucleon
Elliot Leader, Aleksander V. Sidorov, Dimiter B. Stamenov
We present a new NLO QCD analysis of the world data on inclusive polarized deep inelastic scattering. Comparing to our previous analysis: i) the values of g_A and a_8=3F-D are upda…
