Sivers, Boer-Mulders and worm-gear distributions at next-to-leading order

Journal of High Energy Physics, 2023
We compute the Sivers, Boer-Mulders, worm-gear (T and L) transverse momentum dependent distributions in terms of twist-two and twist-three collinear distributions in the small-b limit up to next-to-leading order (NLO) in perturbation theory.

Dynamical NNLO parton distributions

, 2009
Utilizing recent DIS measurements (\sigma_r, F_{2,3,L}) and data on hadronic dilepton production we determine at NNLO (3-loop) of QCD the dynamical parton distributions of the nucleon generated radiatively from valencelike positive input distributions at

Radiation use and understory aboveground net primary production in a temperate dryland

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract We investigated the spatial and temporal variability of herbaceous radiation use efficiency (RUEh$$ {\mathrm{RUE}}_h $$) and herbaceous aboveground net primary production (ANPPh$$ {\mathrm{ANPP}}_h $$) of big sagebrush ecosystems in Wyoming's Upper Green River Basin.

New advances in the statistical parton distributions approach*

EPJ Web of Conferences, 2016
The quantum statistical parton distributions approach proposed more than one decade ago is revisited by considering a larger set of recent and accurate Deep Inelastic Scattering experimental results.

Assessment of Spatial and Temporal Nitrate Dynamics in a Medium‐Sized Watershed Using SWAT‐RIVE

Hydrological Processes, Volume 39, Issue 12, December 2025.
Nitrate dynamics in a catchment with multiple anthropogenic pressures were evaluated with SWAT‐RIVE. The results show that 54% of soil nitrate is removed by denitrification, mainly in agricultural areas and wetlands, 8.5% of nitrate inputs to soils reach the river system, and 1.7% is removed by in‐stream processes.

Generalized parton distributions: recent results

, 2005
I review progress on selected issues connected with generalized parton distributions. Topics range from the description of hard exclusive reactions to the spatial distribution of quarks in the nucleon and the contribution of their orbital angular ...

The improved nuclear parton distributions [PDF]

, 2001
In this paper we propose an improvement of the EKS nuclear parton distributions for the small x region of high energy processes, where the perturbative high parton density effects cannot be disregarded.
