Fig. 6

Transverse momentum distributions of nonprompt (left) electrons and (right) muons in simulated tt¯+jets events, for the three cases “nominal”, “relaxed, fi from tt¯+jets”, and “relaxed, fi from multijet” discussed in text. The figure illustrates that a nonclosure correction needs to be applied to the probabilities fi measured for electrons in data, while no such correction is needed for muons
