| Popis: |
Elastic ..omega..-meson photoproduction on protons has been measured from 46 to 180 GeV. The cross section is approximately constant with photon energy and averages 1.10 +- 0.08 ..mu..b. The t dependence of the differential cross section is consistent with A exp(bt), where b=8.4 +- 0.7 GeV/sup -2/. The photon-omega coupling constant, obtained from a normalization of hadron elastic-scattering cross sections to the photoproduction data of this experiment (with use of the vector-meson dominance and an additive quark model), is ..gamma../sub ..omega../ /sup 2//4..pi..=5.4 +- 0.4. |
