| Abstract: | TheΞ - p differential elastic cross section has been measured in the SPS hyperon beam at 102 and 135 GeV/c. In the range 0.012, thet distributions are found to be compatible with the formA exp(Bt) whereB is 7.7±0.4(GeV/c)?2 at 102 GeV/c and 8.2 ±0.5(GeV/c)?2 at 135 GeV/c. The corresponding total elastic cross sections areσ el=4.9±0.7 mb andσ el=5.6±0.9 mb, respectively. These results are compared with the predictions of phenomenological models. |
