Pion and kaon parton distribution functions from basis light front quantization and QCD evolution [PDF]
Physical Review D, 2019 We investigate the parton distribution functions (PDFs) of the pion and the kaon by combining QCD evolution with the basis light front quantization (BLFQ).

Parton Distribution Functions in the CTEQ framework
Dera Natung Government College Research Journal, 2020 Parton distribution functions (PDFs) are important to study the structure of the proton and hence the dynamics of quarks and gluons inside it. We study some of the PDFs from global CTEQ (Coordinated Theoretical-Experimental project on QCD) analysis in a ...

A data-based parametrization of parton distribution functions
European Physical Journal C: Particles and Fields, 2022 Since the first determination of a structure function many decades ago, all methodologies used to determine structure functions or parton distribution functions (PDFs) have employed a common prefactor as part of the parametrization.

Isovector parton distribution functions of the proton on a superfine lattice [PDF]
, 2020 We study isovector unpolarized and helicity parton distribution functions (PDF) of proton within the framework of Large Momentum Effective Theory. We use a gauge ensemble, generated by the MILC collaboration, with a superfine lattice spacing of $0.042 ...

Generalized parton distribution functions of $\rho$ meson
SciPost Physics Proceedings, 2020 We report our recent calculations for the generalized parton distribution functions of the $\rho$ meson with the help of a light-front constituent quark model. The electromagnetic form factors and structure functions of the system are given. Moreover,

Systematic uncertainties in parton distribution functions from lattice QCD simulations at the physical point [PDF]
Physical Review D, 2019 We present a detailed study of the helicity-dependent and helicity-independent collinear parton distribution functions (PDFs) of the nucleon, using the quasi-PDF approach.

Parton Distribution Functions, $\alpha_s$ and Heavy-Quark Masses for LHC Run II [PDF]
, 2017 We determine a new set of parton distribution functions (ABMP16), the strong coupling constant $\alpha_s$ and the quark masses $m_c$, $m_b$ and $m_t$ in a global fit to next-to-next-to-leading order (NNLO) in QCD. The analysis uses the $\overline{\mathrm{

A model calculation of double parton distribution functions of the pion
European Physical Journal C: Particles and Fields, 2018 Two-parton correlations in the pion are investigated in terms of double parton distribution functions. A Poincaré covariant light-front framework has been adopted.
