Fits to data on polarised structure functions and spin asymmetries with power law corrections
J. Bartelski, S. Tatur
We have compared polarized parton densities determined in the NLO QCD fits to polarized structure functions and spin asymmetries. We consider models of such distributions based on…
A determination of gluon spin distribution from the deep inelastic scattering data
J. Bartelski, S. Tatur
In order to determine polarized parton densities in nucleon we have made fits using all experimental data on spin asymmetries measured in the deep inelastic scattering on different…
A new determination of polarized parton densities in the nucleon
J. Bartelski, S. Tatur
In order to determine polarized parton distributions we have made a new NLO QCD fit using all experimental data on spin asymmetries measured in the deep inelastic scattering on dif…
Determination of polarised parton distributions in the nucleon - next to leading order QCD analysis
Stanislaw Tatur, Jan Bartelski, Miroslaw Kurzela
We have made next to leading order QCD fit to the deep inelastic spin asymmetries on nucleons and we determined polarised quark and gluon densities. The functional form for such di…
Phenomenological Analysis of Data on Inclusive and Semi-inclusive Spin Asymmetries
M. Kurzela, J. Bartelski, S. Tatur
We present a phenomenological analysis of data on both inclusive and semi-inclusive spin asymmetries. We examine the impact of the semi-inclusive results presented by SMC on the de…
Deep inelastic ratio and the possible existence of scalar partons in the nucleon
Jan Bartelski, Wojciech Krolikowski, Miroslaw Kurzela
We have performed several fits to find the ratio in different phenomenological models. Our fits seem to leave no room for possible admixture of scalar partons insid…
