where ''q'' is the breakup momentum of the daughter particles and ''q<sub>0</sub>'' is the same, evaluated at ''m<sub>0</sub>''.
where ''q'' is the breakup momentum of the daughter particles and ''q<sub>0</sub>'' is the same, evaluated at ''m<sub>0</sub>''.
The total expression becomes:
The final expression for the measured cross section becomes:

\frac{d^8\sigma}{d\Omega_{b1}\,d\Omega_\omega\,d\Omega_\rho\,d\Omega_\pi} =
\frac{1}{\sqrt{s}k_i}|T_{fi}|^2
