Popis:	The reaction pp → pπ+X was studied at three energies (Tp = 1520, 1805 and 2100 MeV). The analyzing powers of pp → ΔΔ, pp → Δn and pp → pπ+X reactions (0.94 < MX < 1.5 GeV) were extracted between 0° and 17° in the lab, which corresponds to an angular range between 0° and 100° (c.m.). A theoretical analysis was performed based on s-channel contributions in 2+ and 1− intermediate states. The resulting formulas allow us to obtain good fits with experimental data.
