Deuteron Spin Structure Functions at Small Bjorken - x †
نویسندگان
چکیده
We investigate polarized deuteron structure functions at small values of the Bjorken variable, x < 0.1. In this region contributions from the coherent interaction of diffractively excited hadronic states with both nucleons become important. A proper treatment of this process requires an extension of the Glauber-Gribov multiple scattering theory to include spin degrees of freedom. In the kinematic domain of current fixed target experiments we observe that shadowing effects in g d 1 are approximately twice as large as for the unpolarized structure function F d 2. Furthermore at x < 0.1 the tensor structure function b 1 is found to receive significant contributions from coherent double scattering.

Nuclear shadowing in polarized DIS on 6 LiD at small x and its effect on the extraction of the deuteron spin structure function
Nuclear shadowing in polarized DIS on 6 LiD at small x and its effect on the extraction of the deuteron spin structure function g d 1 (x, Q 2) Abstract We consider the effect of nuclear shadowing in polarized deep inelastic scattering (DIS) on 6 LiD at small Bjorken x and its relevance to the extraction of the deuteron spin structure function g d 1 (x, Q 2). Using models, which describe nuclear...
متن کاملSpin Structure Functions g1 and g2 for the Proton and Deuteron
The experiment E155 at SLAC measured the spin structure functions g1 and g2 of the proton and deuteron. The experiment used deep inelastic scattering of 48.3 GeV longitudinally polarized electrons incident on polarized solid 15NH3 and LiD targets. The data taken by three independent spectrometers covered a kinematic range of 0.014 < x < 0.9 and 1 (GeV/c) < Q < 40 (GeV/c). Due to the high lumino...
متن کاملSome Aspects of Nuclear Deep Inelastic Scattering
Nuclear deep inelastic scattering is considered in the framework of a model in which the current operator explicitly satis es Poincare invariance and current conservation. The results considerably di er from the standard ones at small values of the Bjorken variable x. In particular, it is impossible to extract the neutron structure functions from the deuteron data at x < 0:01 and we predict tha...
متن کاملNuclear Modification of Double Spin Asymmetries
We compute nuclear spin dependent structure functions using a dynamical model for bound nucleon densities and hence calculate nuclear modifications to asymmetries observed in recent doubly polarised deep inelastic scattering experiments. We conclude that while the individual densities are changed substantially by nuclear effects, the asymmetries themselves are largely insensitive to these chang...
متن کاملResults and Interpretations of the Spin Structure Experiments at Slac
In the recent experiments E154 and E155 at SLAC the spin-dependent structure functions g 1 , g p 1, and g d 1 of the neutron, proton, and deuteron were measured by scattering longitudinally polarized 48:3 GeV electrons o longitudinally polarized targets. We report on the measurement of g 1 by E154, and on the preliminary results on g p 1 from E155. The SLAC results provide the most precise dete...
