Multi-parton distributions in a proton, the nonperturbative quantities needed to make predictions for multiple scattering rates, are poorly constrained from theory and data and must be modelled.

The muon parton distribution functions [PDF]
We compute the Parton Distribution Functions (PDFs) of the unpolarised muon for the leptons, the photon, the light quarks, and the gluon. We discuss in detail the issues stemming from the necessity of evaluating the strong coupling constant at scales of ...

Three Decades of Soil N<sub>2</sub>O Research-Insights and Gaps. [PDF]
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model
Pion generalized parton distributions and light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model. The properties of pion generalized parton distributions and light-front wave functions are examined separately. Proceeding

The MSHT20 Parton Distribution Functions
We present the new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from a global analysis of the available hard scattering data and superseding the MMHT14 sets.

An analysis of polarized parton distribution functions with nonlinear QCD evolution equations
We present the polarized parton distribution functions from a QCD analysis of the worldwide polarized deep inelastic scattering data, based on the dynamical parton distribution model.

Parton Distribution Functions and Lattice QCD [PDF]
Recently, there have been rapid developments in lattice-QCD calculations of proton structure, especially in the parton distribution functions (PDFs). We overcame a longstanding obstacle and for the first time in lattice-QCD are able to directly calculate

Transverse-momentum-dependent parton distribution functions for spin-1 hadrons
We show transverse-momentum-dependent parton distribution functions (TMDs) for spin-1 hadrons including twist-3 and 4 functions by taking the decomposition of a quark correlation function in the Lorentz-invariant way with the conditions of Hermiticity
