چکیده
The spin-dependent structure function of the deuteron, g 1D , is calculated within a covariant framework. The off-shell structure of the bound nucleon gives corrections to the convolution model at a level of half a percent for x below 0.7, increasing to more than five percent at larger x. Overall, the dominant source of error comes from the lack of knowledge associated with the deuteron D-state, which may introduce an uncertainty in the neutron spin structure function, g 1n , extracted from deuterium data of up to ten percent for x around 0.2.

Further experimental tests for simple relations between unpolarized and polarized quark parton distributions.
Some simple relations between unpolarized and polarized quark parton distributions have direct experimental consequences which will be presented here. In particular, we will see that it is possible to relate the deep inelastic structure functions F2 and g1, both for proton and deuteron, in fair agreement with experimental data.

The nuclear effects in the spin-dependent structure functions g D 1 and b D 2 are calculated in the relativistic approach based on the Bethe-Salpeter equation with a realistic meson-exchange potential. The results of calculations are compared with the non-relativistic calculations. The problem of extraction of the neutron spin structure function, g n 1 , from the deuteron data is discussed. In ...

We investigate the possibility to measure the nonforward gluon distribution function by means of diffractively produced π+π− and K+K− pairs in polarized lepton nucleon scattering. The resulting cross sections are sizable and are dominated by the gluonic contribution. We find large spin asymmetries, both for π+π− and for K+K− pairs. PACS. 12.38.-t, 13.60.-r, 13.60.Le

We discuss various estimates of the magnitude of higher-twist corrections to the Bjorken sum rule in polarized deep inelastic scattering. Talk given by L.M. at the ‘Workshop on the prospects of spin physics at HERA’, DESY-Zeuthen, August 28-31, 1995 On leave of absence from N.Copernicus Astronomical Center, Warsaw, Poland Considerable attention has been paid to measurements of the polarized str...

Recent measurements of unpolarised and polarised nucleon structure functions and F γ 2 are reviewed. The implications for QCD and the gluon momentum distribution are discussed. The status of the understanding of σ γ * p tot in the transition region between real photoproduction and deep-inelastic scattering is summarised briefly.
