Abstract: | Using the Regge pole phase rule for contrilbutions to both amplitudes the DAM is applied to πp elastic scattering in the plab≥10 GeV/c and |t|≤0.8(GeV/c)2 region. It is found that the DAM has a mixed success in describing πp scattering. The p contribution to both amplitudes is in accord with the DAM while the f-non-flip contribution does not have a peripheral zero.The Pomeron imaginary part is in accord with the DAM with a non-negligible Pomeron phase so that the DAM approximation Rep=O is unsatisfactory. There is also a Pomeron-flip contribution contrary to the expectation of the model. The O-flip contribution is taken into account and a small f-flip contribution i s also required. |
