Detailed Description

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

Author
HEPfit Collaboration

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

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