| Abstract: | The cross section for the KL0p elastic scattering has been measured for the first time. The incident momentum and momentum transfer ranges are 3 ?p? 13 GeV/c, 0.1 ? |t| ? 1.3 GeV2. The results are compared to those of other experiments related to ours by isotopic spin conservation, finding agreement with some and discrepancies with others. The differential cross sections have been parametrized in the form Aebt. The coefficients show little or no dependence on energy, with A ? 9.8 mb · GeV?2and b ? 4.7 GeV?2. The effective linear trajectory has been determined and gives α0 = 0.95 ± 0.15, α′ = ?0.35 ± 0.48 GeV?2, in good agreement with dominance by pomeron exchange. |
