Résumé :

Results are presented on the production of K0, K*+(892) and π± in the interaction K+p → K0 + π± + anything at 8.2 and 16 GeV/c. The π± forward and backward dσ dx distributions are of the form exp (-Ax). It is shown that the forward and backward values of A in a quark-quark rest frame change after subtraction of the contributions due to the resonances produced. A comparison is made of dσ dx inclusive cross sections for K0's and K*+(892) with the predictions of a quark model in the fragmentation region. The experimental cross section matches the theoretical predictions for K0's but disagree with those for K*+(892). © 1975.
