Proton spin in leading order of the covariant approach
Original language description
We study the covariant version of the quark-parton model, in which the general rules of the angular momentum composition are accurately taken into account. We demonstrate how these rules affect the relativistic interplay between the quark spins and orbital angular momenta, which collectively contribute to the proton spin. The spin structure functions g1 and g2, corresponding to the many-quark state J=1/2, are studied, and it is shown they satisfy constraints and relations, which fit well the available experimental data including the data on proton spin content ??1/3. The suggested Lorentz-invariant three-dimensional approach for calculation of the structure functions is compared with the approach based on the conventional collinear parton model.
