Tests of the parametrizations of Fragmentation Functions using data on inclusive pion and kaon production in unpolarized collisions from the STAR collaboration and at the NICA project

D. Kotlorz, E. Christova, E. Leader

The goal of this study is to check which, if any, of the published versions of the pion and kaon fragmentation functions is compatible with the STAR data on semi-inclusive pion and…

On the role of the subsidiary fields in the momentum and angular momentum in covariantly quantized QED and QCD

Elliot Leader

The covariant quantization of QED and QCD requires the introduction of subsidiary gauge-fixing and ghost fields and it is crucial to understand the role of these in the energy-mome…

Sensitivity of strange quark polarization to flavor SU(3) symmetry breaking

Ali Khorramian, Elliot Leader, Dimiter Stamenov +1

The polarized strange quark puzzle concerns the fact that the polarized strange quark density extracted from polarized inclusive deep inelastic scattering data is significantly neg…

New study of the Boer-Mulders function: Implications for the quark and hadron transverse momenta

E. Christova, D. Kotlorz, E. Leader

In series of papers the Boer-Mulders function for a given quark flavour has been extracted: (i) from data on semi-inclusive deep inelastic scattering, using the simplifying, but th…

Towards a model independent extraction of the Boer-Mulders function

E. Christova, D. Kotlorz, E. Leader

At present, the Boer-Mulders function for a given quark flavour has been extracted from data on semi-inclusive deep inelastic scattering using the simplifying, but theoretically in…

Tests for the extraction of Boer-Mulders functions

Ekaterina Christova, Elliot Leader, Michail Stoilov

At present, the Boer-Mulders (BM) functions are extracted from asymmetry data using the simplifying assumption of their proportionality to the Sivers functions for each quark flavo…
