Now open the output file in Root:

|
|
--> SetOptFit(1111111)
|
|
function "[3]*exp(x/2.19703)*(1+[2]*cos(x*[0]+[1]))" was fitted
|
|
Asymmetry = 0.42
|
|
|
|
To study pileup background --> natural decay of muons is required.
|
|
This was done in the file 14460:
|
|
|
|
root [10] TFile* f=new TFile("data/his_14460_14460a.v1190.root")
|
|
root [11] hdet_time20_6->Draw() // condition 6 goodEvent_det
|
|
--> SetOptFit(1111111)
|
|
function "[0]*exp(-x/2.19703)+[1]" was fitted
|
|
--> Remember that par0 = 375.8 (Normalisation)
|
|
--> Background from the fit: par1/par0 = 4.4 / 375.8 = 1.2%
|
|
|
|
root [12] hdet_time20_rotref_6->Draw() // condition 6 goodEvent_det
|
|
--> SetOptFit(1111111)
|
|
function "[2]*cos(x*[0]+[1]" is fitted
|
|
--> Asymmetry = 2* par2/Normalisation = 2 * 78.5 / 375.8 = 0.418
|
|
|
|
2nd way how to extract pileup background:
|
|
root [13] hdet_time10_bgr3_6->Draw() // condition 6 goodEvent_det
|
|
--> SetOptFit(1111111)
|
|
--> background = par0/Normalisation = 4.9 / 375.8 = 1.3%
|
|
|
|
3rd way how to extract background:
|
|
root [14] hdet_time10_bgr1_9->Draw() // condition 9 pileupEvent
|
|
--> SetOptFit(1111111)
|
|
--> background = par0/Normalisation = 4.5 / 375.8 = 1.2%
|
|
|
|
Where to the muons and pileup muons stop? :
|
|
root [28] humanDecayHistograms_6->Draw() // <--- accepted events
|
|
root [29] humanDecayHistograms_9->Draw() // <--- mu1 for pileup events
|
|
root [30] humanDecayPileupHistograms_9->Draw() // <--- mu2 for pileup events
