BDT numbers sorted into different xG bins

These numbers have been sorted into three different xG bins i.e 0.0-0.05(inclusive), 0.05-0.1(inclusive) and 0.1-0.3(inclusive).

pT > 7GeV cut has been applied.

(I) Overtraining Check Plots

 

(a) xG (0.0-0.05)                                                                                            (b) xG (0.05-0.1)

  

(c) xG (0.1-0.3)

 

II) Background rejection vs signal efficiency plots

(a) xG (0.0-0.05)                                                                                            (b) xG (0.05-0.1)

  

(c) xG (0.1-0.3)

(III) Efficiency plots

 

(a) xG (0.0-0.05)                                                                                            (b) xG (0.05-0.1)

  

(c) xG (0.1-0.3)
