Data sample is splitted in 4 sub-sample:
Split sample 2
- Ds+ High momentum
- Ds- High momentum
- Ds+ Low momentum
- Ds- Low momentum
Split sample 1
- SST High momentum
- SST High momentum
- SST Low momentum
- SST Low momentum
- Fit Variant Systematic:
- different parameterization of efficiency
- different parameterization of background
- different version of Pythia
We compute the c2/ n.d.o.f = (where < x > is the weighted average and N = 4)
? only if c2/ n.d.o.f > 1 we have a systematic effect .
