Detailed Description

A class for the binned observable \(<A_{FB}>\) in \(M \to V l^+l^-\).

Author
HEPfit Collaboration

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

\[ <A_{FB}>=- \frac {3<\Sigma_{6s}>}{4<\Gamma'>} \,. \]
