Résumé : We present results on inclusive φ meson production in K+p interactions at 70 GeV/c in the kaon fragmentation x>0.2 region. Comparison with other data on φ meson production in K± and p induced reactions provides evidence that the strange valence-quark fragmentation or recombination processes play the dominant role in the K±→φ transitions. Arguments are presented that the kaon valence strange s-quark carries a much higher momentum fraction than the u-quark. Evidence for the previously observed narrow φπ+ state at mass ∼2.1 GeV is discussed. © 1982.
