Abstract | |||||||||||||||
| We report on a measurement of the branching ratio of the rare decay #### relative to the well known decay ### 0 #. The #'s are produced in pp### and pp## 0 #. Eigenstate mixing and interference e#ects of the # and # 0 are taken into account, as well as coherent interference with the background. We find evidence for the non-resonant annihilation channel BR(pp####) = (3.5 1.3)10 -5 and limit the value of BR(####) to the range of (0.7 to 5.5)10 -4 depending on the degree of coherence with the background. 13.20.Jf Decays of other mesons Typeset using REVT E X 3 I. INTRODUCTION Radiative meson decays have been used to test various models of non-perturbative QCD, such as the quark model and vector dominance. The family of radiative vector meson to pseudoscalar meson (or vice versa) decays includes 11 di#erent decays. Of these, the decay #### (1.1) is the focus of this experiment. The decay # 0 ### is also poorly known, but because of the larger # 0 width, is more di#cu... | |||||||||||||||
