Parton Distribution Functions in Hadron and Decay Distribution Functions in the New Type of Quark Cascade Model

Parton Distribution Functions for the Large Hadron Collider

Precise knowledge of the parton distribution functions (PDFs) of the proton is essential to relate data to theory at the Large Hadron Collider (LHC). I will give an overview of the determination of proton PDFs from global analysis of existing data taken at HERA, the Tevatron and fixedtarget experiments. Recent developments and current status will be described. In particular, a comparison will b...

Parton distribution functions in nuclei

Optimum nuclear parton distributions are determined by an analysis of muon and electron deep inelastic scattering data. Assuming simple A dependence and polynomial functions of x and 1−x for nuclear modification of parton distributions, we determine the initial distributions by a χ 2 analysis. Although valence-quark distributions are relatively well determined except for the small-x region, ant...

Dynamical parton distribution functions

Recent measurements for F2(x, Q ) have been analyzed in terms of the ‘dynamical’ and ‘standard’ parton model approach at NLO and NNLO of perturbative QCD. Having fixed the relevant NLO and NNLO parton distributions, the implications and predictions for the longitudinal structure function FL(x,Q ) are presented. It is shown that the previously noted extreme perturbative NNLO/NLO instability of F...

Nuclear Parton Distribution Functions

We study nuclear e ects of charged current deep inelastic neutrino-iron scattering in the framework of a χ analysis of parton distribution functions (PDFs). We extract a set of iron PDFs which are used to compute xBj-dependent and Q -dependent nuclear correction factors for iron structure functions which are required in global analyses of free nucleon PDFs. We compare our results with nuclear c...
