Abstract
TheΞ - p differential elastic cross section has been measured in the SPS hyperon beam at 102 and 135 GeV/c. In the range 0.01<−<0.42(GeV/c)2, 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.

Taking only the imaginary part of the non-spin flip amplitude into account, as Carlitz does for meson baryon scattering, we find the following slope relation att=0:\(\frac{{B(\Xi p) - B(pp)}}{{B(Kp) - B(\pi p)}} = \frac{{2(1 + r)}}{{1 - \varepsilon + 2r}}.\) The value ofr is estimated from the ratioσ T (Kp)/σ T (πp) [13] extrapolated to larges (≈1 TeV2) and is found to be 0.73 [14]. For ε, the experimental ratioσ T (Ξ - p)/σ T (pp yields 0.75 ±0.19 (in contradiction with the value −1/3 used by Carlitz). We set\(B(Kp) = \tfrac{1}{2}\left[ {B(K^ + p) + B(K^ - p)} \right] and B(\pi p) = \tfrac{1}{2}\left[ {B(\pi ^ + p) + B(\pi ^ - p)} \right]\)
