Detailed Description

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

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

\[ <{R_T}>_{M \to V l^+ l^-}= \frac {<\Gamma'>_{M \to V l_1^+l_1^-}(1-<{F_L}>_{M \to V l_1^+l_1^-})}{<\Gamma'>_{M \to V l_2^+l_2^-}(1-<{F_L}>_{M \to V l_2^+l_2^-})} \,. \]
