Backward omega /sup 0/ and eta /sup 0/ production in pi p interactions at 9 and 12 GeV/c

The backward production of omega /sup 0/ mesons in the u-channel I/sub u/=/sup 1///sub 2/ exchange reaction pi /sup -/p to N/sup 0/ (1680) omega /sup 0/ has been studied at 9 GeV/c and 12 GeV/c incident momenta. The data comes from an experiment performed at the CERN Omega Spectrometer using a fast...

Descripción
Sumario:The backward production of omega /sup 0/ mesons in the u-channel I/sub u/=/sup 1///sub 2/ exchange reaction pi /sup -/p to N/sup 0/ (1680) omega /sup 0/ has been studied at 9 GeV/c and 12 GeV/c incident momenta. The data comes from an experiment performed at the CERN Omega Spectrometer using a fast proton trigger device. The backward production of the eta /sup 0/ meson has also been observed and the coupling constant ratio g/sub eta NN//g/sub pi NN/ has been estimated. (21 refs).
