Abstract The main aim of this paper is to present new sets of non-perturbative fragmentation functions (FFs) for $$D^0$$ D0 and $$D^+$$ D+ mesons at next-to-leading (NLO) and, for the first time, at next-to-next-to-leading order (NNLO) in the $$\over

We present SKMHS22, a new set of diffractive parton distribution functions (PDFs) and their uncertainties at next-to-leading-order and next-to-next-to-leading-order accuracy in perturbative QCD within the xFitter framework. We describe all available

We study the impact of intrinsic strange (IS) component of nucleon sea on the global analysis of parton distribution functions (PDFs) considering a wide range of experimental data. To this aim, we consider two scenarios on the basis of BHPS model res

In this work, using the Laplace transformation technique we present our results for non-singlet quark distributions as well as nucleon structure function $F_2(x,Q^2)$ in unpolarized case at next-to-next-to-leading order (NNLO) QCD accuracy. We shall

The hadronization mechanism is described by the fragmentation functions (FFs) which are universal and process-independent quantities. They can be generally determined theoretically or phenomenologically. In the phenomenological approach which is base

We present nonperturbative fragmentation functions (FFs) for bottom-flavored (B) hadrons both at next-to-leading (NLO) and, for the first time, at next-to-next-to-leading order in the ¯¯¯¯¯¯MS factorization scheme with five massless quark flavo

In this paper, we present {\tt SMKA18} analysis which is a first attempt to extract the set of next-to-next-leading-order (NNLO) spin-dependent parton distribution functions (spin-dependent PDFs) and their uncertainties determined through the Laplace

The experimental data taken from both Drell-Yan and deep-inelastic scattering experiments suggest a sign change in $\overline{d}(x)\ensuremath{-}\overline{u}(x)$ flavor asymmetry in the proton at large values of momentum fraction $x$. In this work, w

Precise knowledge of the strange and antistrange quark distributions of the nucleon is a major step toward better understanding of the strong interaction and the nucleon structure. Moreover, the $ s-\bar s $ asymmetry in the nucleon plays an importan
