In addition to the (s, t, u)-channel Born diagrams, we take into account various baryon-resonance contributions such as F15(2000), D13(2080), G17(2190), D15(2200), F35(2000), G37(2200), F37(2390), and Sigma*(1385, 3/2+) in a fully covariant manner. We present the numerical results for the energy and angular dependences for the cross sections in comparison to available experimental data.
