Detailed Description

A class for the binned observable ratio \(\frac {<BR_L>_{M \to V l_1^+l_1^-}}{<BR_L>_{M \to V l_2^+l_2^-}}\) in \(M \to V l^+l^-\).

This class is used to compute the binned observable longitudinal ratio \(\frac {<BR_L>_{M \to V l_1^+l_1^-}}{<BR_L>_{M \to V l_2^+l_2^-}}\) in \(M \to V l^+l^-\) in terms of the binned observables \(<\Gamma'>_{M \to V l_i^+l_i^-}\) and \(<{F_L}>_{M \to V l_i^+l_i^-}\):

\[ <{R_L}>_{M \to V l^+ l^-}= \frac {<\Gamma'>_{M \to V l_1^+l_1^-}<{F_L}>_{M \to V l_1^+l_1^-}}{<\Gamma'>_{M \to V l_2^+l_2^-}<{F_L}>_{M \to V l_2^+l_2^-}} \,. \]
