Detailed Description

A class for the binned observable \(<\Gamma'>\) in \(M \to V l^+l^-\).

Author
HEPfit Collaboration

This class is used to compute the binned observable \(<\Gamma'>\) in \(M \to V l^+l^-\) in terms of the binned CP averaged helicity coefficients \(<\Sigma_i>\), computed in the MVll class:

\[ <\Gamma'>=- \frac {1}{4} (<(3\Sigma_{1c} - \Sigma_{2c}) + 2(3\Sigma_{1s} - \Sigma_{2s})>)\,. \]
