The Spin Dependence of Diffractive Processes and Implications for the Small x Behaviour of g1 and the Spin Content of the Nucleon
F. E. Close, R. G. Roberts
Abstract
We show that if the Lorentz transformation properties of diffraction are other than scalar, the x → 0 behaviour of g1(x,Q2) can grow. We compare with new data on g1p from SMC, assess implications for sum rules and for future studies of sea polarisation.
