pp annihilation into K0K0 in hydrogen gas

Academic Article


  • The annihilation channels pp→KsKs and KsKL at rest have been observed in hydrogen gas at normal temperature and pressure. The channel KsKs has also been observed from the atomic 2p orbital. The branching fraction for pp→K0K0 from initial L = 1 angular momentum pp states is (8.8±2.3)×10-5 and is suppressed by one order of magnitude compared to L = 0 states. © 1988.
