Abstract

Experimental results concerning the kaon yield in the reaction d + Be → K ±(0°) + X for values of the cumulative variable x c in the range between 0.88 and 1.37 are presented. Values in the region of x c ≥ 1 correspond to short nucleon-nucleon distances (deuteron-core region) at which nucleon wave functions begin overlapping each other, forming a cluster (flucton) where the hadron-matter density is higher than the average matter density in the nucleus. The behavior of the K +/K yield ratio in this region may be interpreted within the hypothesis that the quark sea in nuclei becomes harder because of the presence of a flucton component in nuclear matter.
