A diffractive model including spin for pp elastic scattering at very high energy

In this paper we present a theoretical diffractive model for spin-dependent proton-proton scattering at very high energies using an extended version of the Chou-Yang model. The model describes a wide t range, but in this paper we use it for small t values. We obtain estimates of the ratio of spin-dependent to spin-independent amplitudes, β, consistent with a previous phenomenological analysis. Next we estimate the asymmetry, Σ, expected in a certain polarized inclusive process at high energy. We then compute the size of polarization effects in pp total cross-section measurements, using polarized beam and target at very high energy. Our estimates of the latter two quantities indicate that their measurement would not provide a sensitive test of pomeron factorization.
