Validation of MC Templates

The shape of the signal distribution will be validated using a data-driven method. A data sample with a high -content will be used to cross-check the shape of the 

The light quark background is dominated by the fake muon contribution and can therefore be estimated from data. If the muon fake probability is known, the light quark background can be measured by re-weighting the hadron spectrum in minimum bias events by the fake muon probability. 

In order to calculate the muon probability for tracks in an inclusive data sample, the composition of the minimum bias track spectrum has to be known. This information is taken from theMC simulation where the hadronic spectram consists of 62% pions, 15% kaons and 19% baryons. The fake probability depends on the track transverse
