Abstract: (arXiv)
We have measured inclusive data on -meson production in collisions at COSY Juelich close to the hyperon production threshold and determined the hyperon-nucleon invariant mass spectra. The spectra were decomposed into three parts: , and . The cross sections for the later channel were found to be much smaller than a previous measurement in that excess energy region. The data together with previous results at higher energies are compatible with a phase space dependence.Note:
