Abstract
The ~b~r+/toTr + ratio from hp annihilations on a liquid hydrogen target, for h momenta between 64 and 297 MeV/c, was measured using the OBELIX spectrometer at LEAR. The raUo R(dpTr/torr) = tr(~p --~ dp~r+)/tr(hp ~ tour +) turned out 0.110 + 0.015star 4- 0.006syst. Implications of this result on the OZI rule are discussed.File in questo prodotto:
