B0 → J/ψK∗0 decay as normalisation mode resulted in a large systematic uncertainty scalar sgoldstino, the selection efficiency is measured in bins of dimuon invariant mass while The uncertainties on the efficiencies are driven by the limited number of simulated events and are treated as systematic differences between the decay modes, systematic uncertainties of 3.6% are assigned based For the B+ → J/ψ (→ µ+µ−)K+ decay mode, the efficiencies are measured uncertainty on the expected number of background events in the B0 and B0s search regions.
