Scheme Dependence in Polarized Deep Inelastic Scattering
We study the effect of scheme dependence upon the NLO QCD analysis of the world data on polarized DIS. The reliability of an analysis at NLO is demonstrated by the consistency of our polarized densities with the NLO transformation rules relating them to each other. We stress the importance of the chiral JET scheme in which all the hard effects are consistently absorbed in the Wilson coefficient...
متن کاملStatus of Polarized and Unpolarized Deep Inelastic Scattering
The current status of deep inelastic scattering is briefly reviewed. We discuss future theoretical developments desired and measurements needed to further complete our understanding of the picture of nucleons at short distances. Invited talk, DIS 2005, Madison, WI; Duality05, LNFN, Frascati, Italy.
متن کاملQCD Analysis of Polarized Deep Inelastic Scattering Data
A QCD analysis of the world data on inclusive polarized deep inelastic scattering of leptons on nucleons is presented in leading and next–to–leading order. New parameterizations are derived for the quark and gluon distributions and the value of αs(MZ) is determined. Emphasis is put on the derivation of fully correlated error bands for these distributions which are directly applicable to determi...
متن کاملNLO QCD Analysis of Polarized Deep Inelastic Scattering
We have carried out a NLO analysis of the world data on polarized DIS in the MS scheme. We have studied two models of the parametrizations of the input parton densities, the first due to Brodsky, Burkhardt and Schmidt (BBS) which gives a simultaneous parametrization for both the polarized and unpolarized densities and in which the counting rules are strictly imposed, the second in which the inp...
متن کاملInstanton-induced charm contribution to polarized deep-inelastic scattering
Recent data on B decays involving η′ may be explained if the singlet axial current of charmed quarks has a large matrix element to η′, and instantons were shown to be able to generate this effect. We study the magnitude of charm contributions to nucleon polarized structure functions generated in a similar way. Comparing the charm contribution, which is related to a dim(6) gluonic operator, to t...
