Role of strange and charm quarks in the nucleon spin structure function.

چکیده
We perform an analysis of the relation between the factorization scale and the masses of the quarks in the calculation of the hard gluon coefficient in polarized deep inelastic scattering. Particular attention is paid to the role of strange and charm quarks at finite momentum transfer. It is found that for the momentum transfer of the present experiments, the contribution from the charm quark is significant.

The Quarkkantiquark Asymmetry of the Nucleon Sea
Although the distributions of sea quarks and antiquarks generated by leadingtwist QCD evolution through gluon splitting g ! qq are necessarily CP symmetric, the distributions of nonvalence quarks and antiquarks which are intrinsic to the nucleon's bound state wavefunction need not be identical. In this paper we investigate the sea quark/antiquark asymmetries in the nucleon wavefunction which ar...

We present the recent investigation on the effect of the SU(3) symmetry breaking in the spin structure of the octet baryons. The spin structure of the nucleon has been a hot issue since the measurement of the first moment of the proton spin structure function g p 1 [1] by the European Muon Collaboration (EMC). The EMC result indicates that the strange quark is polarized in the opposite directio...
متن کاملChiral symmetry and the charge asymmetry of the ss-bar distribution in the proton.
Recently it has been suggested that a sizeable fraction of the strange and charm quarks in a nucleonthe so-called “intrinsic strangeness or charm”have momentum distributions which extend to large Xbj. This effect is enhanced if these virtual heavy quarks live long enough such that many interactions with the rest of the nucleon can occur. It is shown that the same mechanism responsible for the i...
متن کاملMass Effects on the Nucleon Sea Structure Functions
Nucleon sea structure functions are studied using Dokshitzer-Gribov-Lipatov-AltarelliParisi (DGLAP) equations with the massive gluon-quark splitting kernels for strange and charm quarks, the massless gluon-quark splitting kernels for up and down quarks, and the massless kernels for all other splitting parts. The SU(2)f flavor symmetry for two light quarks, ‘up’ and ‘down’, is assumed. Glück-Rey...
