Extracting Parton Densities from Collider Data
Collider data can play an important role in determining the parton distribution functions of the nucleon. I present a formalism which makes it possible to use next-to-leading order calculations in such a determination, while minimizing the amount of numerical computation required. Submitted to Nuclear Physics B Laboratory of the Direction des Sciences de la Matière of the Commissariat à l’Energ...

متن کاملGRSV parton densities revisited
R = FL/2xF1, in longitudinally polarized DIS off various different targets (p, n, d) have become available in the past two years: E142, E143, and SMC have presented their final data sets [ 1], and new results from HERMES, E154, and E155 have been reported recently [ 2]. Since none of these measurements were included in our original NLO QCD analysis [ 3], it seems to be appropriate to reanalyse ...
متن کاملProbing the parton densities of polarized photons at a linear e+e− collider
The present theoretical status of spin-dependent parton densities ∆f(x, Q) of circularly polarized photons is briefly reviewed. It is then demonstrated that measurements of the deep-inelastic spin asymmetry Aγ1 ≃ gγ 1 /F γ 1 and of di-jet rapidity distributions at a future linear e e collider appear to be particularly suited for a determination the spin-dependent photonic quark and gluon densit...
متن کاملParton Densities in a Nucleon
In this paper we re-analyse the situation with the shadowing corrections (SC) in QCD for the proton deep inelastic structure functions. We reconsider the Glauber Mueller approach for the SC in deep inelastic scattering (DIS) and suggest a new nonlinear evolution equation. We argue that this equation solves the problem of the SC in the wide kinematic region where αS κ = αS 3παS 2QR xG(x,Q) ≤ 1. ...
