Detailed Description

A class for the binned integrated observable \(<BR>\) in \(M \to P l^+l^-\).

This class is used to compute the binned-integrated observable \(<BR>\) in \(M \to P l^+l^-\) in terms of the binned CP averaged helicity coefficients \(<\Sigma_i>\), computed in the MPll class, and the meson width \(W_M\):

\[ <BR>= \frac {<\Gamma'>}{W_M} \,. \]
