Mesures des sections efficaces différentielles $K^{0}P \to K^{0}_{s}p$ dans l'intervalle d'impulsion 4-14GeV/c et dans l'intervalle de transfert $0,l-2GeV^{2}$

Experimental data on the Ksub(L)sup(o)p→Ksub(S)sup(o)p reaction between 4 and 14 GeV/c in the range 0.1< approximately /t/ < approximately 2 GeV2 are presented. This experiment has been performed at the C.E.R.N. P.S. using spark chambers and a large aperture magnet. The results show a break of slope at t=-0.3 GeV2. The ω trajectory deduced from the data has an intercept α(0)=0.5 and a slope α'=0.88. A comparison with various models shows that the non-flip amplitude is dominant
