Query: Energy dependence of the Lambda/Sigma0 production cross section ratio in
  p-p interactions   Measurements of the near threshold Lambda and Sigma0 production via the
pp-->pK+Lambda/Sigma0 reaction at COSY--11 have shown that the Lambda/Sigma0
cross section ratio exceeds the value at high excess energies Q>=300 MeV by an
order of magnitude. For a better understanding additional data have been taken
between 13 MeV and 60 MeV excess energy. Within the first 20 MeV excess energy
a strong decrease of the cross section ratio is observed, with a less steep
decrease in the higher excess energy range. A description of the data with a
parametrisation including p-Y final state interactions suggests a much smaller
p-Sigma0 FSI compared to the p-Lambda system.
