Abstract
In this work the production of the state is estimated via the reaction through triangle mechanisms described by the sequence . The molecular configuration of the is considered. By means of the effective Lagrangian approach, the branching ratio is calculated as a function of the strength of the coupling of the charged components to the and compared with experimental data. Besides, employing the decay as a normalization channel, the ratio of branching fractions is also estimated. The findings provide another concrete example for the vital role of charged components in achieving a quantitatively correct description of the .
