Instanton Contribution to Polarized and Unpolarized Gluon Distributions in Nucleon
نویسنده
چکیده
The contribution of the anomalous quark-gluon interaction induced by instantons to the polarized and unpolarized gluon distributions in nucleon is estimated. It is shown that this interaction leads to negative gluon polarization in nucleon.

We show that the instanton model of the QCD vacuum indicates the parametric smallness of the twist-3 contributions to the polarized structure function h L. This smallness is related to the diluteness of the QCD instanton vacuum. 1. Among higher twist parton distributions the twist-3 distributions play a special role. In many physical observables the twist-3 distributions enter not suppressed by...
متن کاملPerturbative Evolution of Polarized Structure Functions
We review the perturbative evolution of the polarized structure functions g1 and their associated parton distribution functions, with particular emphasis on the anomalous coupling of the first moment of the polarized gluon distribution. We also describe the small x behaviour of polarized parton distributions, contrasting it with that of the unpolarized distributions. We then explain how this th...
متن کاملGluon Polarization from QCD Sum Rules
The gluon polarization ∆G in a nucleon can be defined in a gauge invariant way as the integral over the Ioffe-time distribution of polarized gluons. We argue that for sufficiently regular polarized gluon distributions ∆G is dominated by contributions from small and moderate values of the Ioffe-time z ∼ 10. As a consequence ∆G can be estimated with 20% accuracy from the first two even moments of...
متن کامل0 Polarization in Hadronic Λ Hyperon Production and Twist - 3 Quark Distribution
Polarization of the Λ hyperon produced with a large transverse momentum in the unpolarized nucleon-nucleon collision is analyzed in the framework of QCD factorization. We focus on the mechanism in which the soft-gluon component of the chiral-odd spin-independent twist-3 quark distribution EF (x, x) becomes a source of the polarized quark fragmenting into the polarized Λ. Our simple model estima...
