Abstract
We measured the ratios of electroproduction cross sections from a proton target for three exclusive meson-baryon final states: , , and , with the CLAS detector at Jefferson Lab. Using a simple model of quark hadronization, we extract creation probabilities for the first time in exclusive two-body production, in which only a single pair is created. We observe a sizable suppression of strange quark-antiquark pairs compared to nonstrange pairs, similar to that seen in high-energy production.
