additional MC weight on the signal sample
- rootfile of signal sample is created with an additional branch of weight for consistency among all decay channels;
- values in this nominal branch should not be used really as a event weight in the final calculation;
- so we cancel this factor when defining the additional MC weight for the signal sample:

- specifications for bbtautau decay channel because of category-sensitive branching ratios of tau lepton in signal sample

[wrong weight setup for bkg sample in stage-1 config]

[original bkg distribution]


- actual bkg yield: 1004.2557.
- expected HL yields: 98478.25978.
