, 2004 I discuss our current understanding of parton distributions. I begin with the underlying theoretical framework, and the way in which different data sets constrain different partons, highlighting recent developments.

Proton Spin Structure from Measurable Parton Distributions
, 2012 We present a systematic study of the proton spin structure in terms of measurable parton distributions. For a transversely-polarizedproton, we derive a polarization sum rule from the leading generalized parton distributions appearing in hard exclusive ...

Journal of Agricultural Economics, EarlyView.ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

Parton distributions in the photon
Zeitschrift für Physik C Particles and Fields, 1994 We discuss in detail the photon structure function beyond the leading logarithm approximation. Of special concern is the factorization scheme and the hadronic input; we show how to naturally absorb large terms due to the MSbar factorization scheme in a modified hadronic component.

A model for the parton distributions in hadrons [PDF]
Physics Letters B, 1998 A simple model is presented for the parton distributions in hadrons. The parton momenta in the hadron rest frame are derived from a spherically symmetric, Gaussian, distribution having a width motivated by the Heisenberg uncertainty relation applied to the hadron size.

Child &Family Social Work, EarlyView.ABSTRACT Supervision is integral to social work practice; however, how it operates in day‐to‐day practice remains poorly understood. Existing research mainly comprises quantitative and qualitative accounts of social workers' and supervisors' experiences of supervision.

Kaon and pion parton distributions
European Physical Journal C: Particles and Fields, 2020 Beginning with results for the leading-twist two-particle distribution amplitudes of $$\pi $$ π - and K-mesons, each of which exhibits dilation driven by the mechanism responsible for the emergence of hadronic mass, we develop parameter-free predictions ...

Journal of Fish Biology, EarlyView.Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Generalized parton distributions and the dependence of parton distributions on the impact parameter [PDF]
AIP Conference Proceedings, 2001 Generalized parton distributions (GPDs) provide a link between form factors, parton distributions and other observables. I discuss the connection between GPDs and parton distributions as a function of the impact parameter. Since this connection involves GPDs in the limit of vanishing skewedness parameter $ξ$, i.e.

Covariant extension of the GPD overlap representation at low Fock states
European Physical Journal C: Particles and Fields, 2017 We present a novel approach to compute generalized parton distributions within the lightfront wave function overlap framework. We show how to systematically extend generalized parton distributions computed within the DGLAP region to the ERBL one ...
