Supposing there exists an effective charge which defines an evolution scheme for both unpolarised and polarised parton distribution functions (DFs) that is all-orders exact and using Ansätze for hadron-scale proton polarised valence quark DFs, const

Publikováno v: Symmetry, Vol 14, Iss 8, p 1530 (2022)

In the framework of a multi-source thermal model at the partonic level, we have analyzed transverse momentum spectra of hadrons measured by the ALICE Collaboration in proton–proton (pp or p–p) collisions at the center-of-mass energy of s=7 and 13
