摘要：

We report measurements of the decays c+pK»0, c+pK»0+-, c+0+, and c+0++- from Fermilab photoproduction experiment E691. We have measured the relative branching ratios B(c+pK»0)B(c+pK-+)=0.55±0.17±0.14, B(c+0++-)B(c+pK-+)=0.82±0.29±0.27, B(c+0+)B(c+pK-+)<0.33 at 90% confidence level, and B(c+pK»0+-)B(c+pK-+)<1.7 at 90% confidence level. © 1990 The American Physical Society.
