• 論文の詳細を見る

• Using modularized NaI(Tl) detectors, we carried out a high-statistics measurement of inclusive π゜ and n spectra in antiproton annihilation at rest in a liquid D_2 target. We obtained the following two-meson yields (branching ratios) per p^^-N (N = p or n) annihilation: 0.19 ± 0.09% for π゜ω, 1.07 ± 0.19% for π゜ρ゜, 0.057 ± 0.018% for π゜η, 0.0123 ± 0.0055% for π゜π゜, 0.02 ± 0.02% for π゜ρ^-, 0.202 ± 0.031% for π゜π^-, 0.49 ± 0.12% for ηω, 0.45 ± 0.15% for ηρ゜, and 0.91 ± 0.22% for ηρ^-.
