ON THE Q(2) DEPENDENCE OF THE MEASURED POLARIZED STRUCTURE FUNCTIONS

We analyse the available data on the polarized asymmetries A(1) for pr oton, neutron and deuteron targets. We use a homogeneous and updated s et of unpolarized structure functions to derive g(1) from A(1), and we accurately correct for the scaling violations in order to obtain g(1) (x, Q(2)) with the same Q(2) for all x values. The contribution to the Q(2) evolution of a possible large gluon polarized density is also co nsidered. The implications for the Ellis-Jaffe and for the Bjorken sum rules are discussed.
