Move some part from the DHadronic.muse to here:
Fit MC samples
Look at biases on the extracted mass with respect to the truth - and across modes.
Signal MC
- Select D0_to_Kpi and D0B_to_Kpi event:
$c3python myyields.py signal --single
Selected event plots:
- Prepare the text file for fit
| signal_Single_D0_to_Kpi.evt |
Combine the D0 and D0B together
signal_Single_D0_D0B_to_Kpi.evt
- Fit Mbc
$cd Roofit $. setup.sh $c3python single_tag_fit.py --mode 0 --file \ signal_Single_D0_D0B_to_Kpi.evt mc
- Fit result plots
After done the same thing for the D+ and D-, one get:
single_Single_D0AndD0B_to_Kpi.eps
single_Single_DpAndDm_to_Kpipi.eps
Generic MC
- Plots
generic_Single_D0AndD0B_to_Kpi
generic_Single_DpAndDm_to_Kpipi
Fit Data
Compare the mass difference you find to the assumptions made in the beam energy correction determination. Is there an inconsistency? If so what are the implications?
- Fit reslults
New Script DHad.py
D0_to_Kpi Signal MC
c3python DHad.py -t s -m 0 --tag s --sign 1
