Parton distribution functions [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 Parton distribution functions give the probability to find partons (quarks and gluons) in a hadron as a function of the fraction x of the proton's momentum carried by the parton. They are conventionally defined in terms of matrix elements of certain operators.

A parton shower consistent with parton densities at LO and NLO: Pdf2Isr
European Physical Journal C: Particles and FieldsWe present a method for obtaining an initial-state parton shower model where the (backward) evolution fully consistent with the (forward) evolution of the collinear parton density used.

The multidimensional nucleon structure
EPJ Web of Conferences, 2016 We discuss different kinds of parton distributions, which allow one to obtain a multidimensional picture of the internal structure of the nucleon.

Universality of the EMC Effect
, 2005 Using effective field theory, we investigate nuclear modification of nucleon parton distributions (for example, the EMC effect). We show that the universality of the shape distortion in nuclear parton distributions (the factorisation of the Bjorken x and

Implementing potential climate‐smart practices through diverse partnerships
PLANTS, PEOPLE, PLANET, EarlyView.Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Nonforward parton distributions [PDF]
Physical Review D, 1997 Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of usual parton distributions for the case when long-distance information is accumulated in nonforward matrix elements of quark and gluon light-cone operators.

Double parton distributions in the leading logarithm approximation of perturbative QCD
, 2003 Recent CDF measurements of the inclusive cross section for a double parton scattering attach a great importance to any theoretical calculations of two-particle distribution functions.

Quasi-parton distribution functions, momentum distributions, and pseudo-parton distribution functions [PDF]
, 2017 We show that quasi-parton distribution functions (quasi-PDFs) may be treated as hybrids of PDFs and primordial rest-frame momentum distributions of partons. This results in a complicated convolution nature of quasi-PDFs that necessitates using large p3≳3

Parton physics on a quantum computer [PDF]
Physical Review Research, 2019 Parton distribution functions and hadronic tensors may be computed on a universal quantum computer without many of the complexities that apply to Euclidean lattice calculations.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
