Abstract
Subject headings
Close
- The inclusive η-momentum spectrum from Mathematical expression annihilations at rest in liquid hydrogen was measured at LEAR. Branching ratios were obtained for Mathematical expression, and ηη(8.1±3.1)Ã10-5. An upper limit for Mathematical expression of 1.8Ã10-4 at 95% CL was found. The ratio of the branching ratios is BR(ηÏvariant)/BR(ηÏ)=0.51-0.06+0.20. For the ratio of branching ratios into two pseudoscalar mesons, we have BR(ηÏ0)/BR(Ï0Ï0)=0.65±0.14, BR(ηη)/BR(Ï0Ï0), BR(ηηâ²)/BR(Ï0Ï0) at 95% CL, and BR(ηη)/BR(ηÏ0). © 1989 Springer-Verlag.
