Two issues have been identified in the measurement of the differential branching fraction of B0→K*(892)0µ+µ- decays presented in ref. . Both of these issues involve the calculation of the ratio of efficiencies between the decay(Formula presented.)(normalisation mode) and the decay B0→K*(892)0µ+µ- (signal mode), denoted as Rϵ in eq. (7.1) of ref. . What follows is a brief description of the nature of these problems, followed by the corrected results.
