ρ0-ω Interference in Antiproton Annihilations at 0.65-1.1 GeV/c
Abstract
Evidence for ρ0-ω interference observed in the π+π- mass spectrum from the annihilation p̄p→π+π+π-π- at incident momenta between 0.65 and 1.1 GeV/c is presented. The best-fit values for the branching ratio R(ω→π+π-ω→π+π-π0), phase , and coherence factor α are 1.3%, 100°, and 0.95. © 1973 The American Physical Society.
