BDT numbers sorted into different pT bins

These numbers have been sorted into three different pT bins i.e 7-10(inclusive), 10-15(inclusive) and 15-20(inclusive).

(I) Overtraining Check Plots

 

(a) pT (7-10)                                                                                            (b) pT (10-15)

  

(c) pT (15-20)

II) Background rejection vs signal efficiency plots

(a) pT (7-10)                                                                                            (b) pT (10-15)

  

(c) pT (15-20)

 

(III) Efficiency plots

(a) pT (7-10)                                                                                            (b) pT (10-15)

  

(c) pT (15-20)

 Difficult to model because of

limited statistics
