1 Thesis topics converted photon and pi0 discrimination
standalone muon efficiency with cosmic muon data(CRAFT) constrains on HVV coupling constants via maximum likelihood method

2 Converted photon and pi0 discrimination
1 track case 2 track case

3 Input variables for 1 track case

4 Input variables for 2 track case

5 BDT response 1 track case 2 track case

6 Apply on γjet sample 1 track case 2 track case 47% 53% 47% 48% -0.21
-0.28

7 If I train the γjet sample and apply the way on jets sample, what will happen?

8 pi0 rejection 1 track case 2 track case

9 Input variables for 1 track case

10 Input variables for 2 track case

11 BDT response 1 track case 2 track case

12 Apply on jets sample 1 track case 2 track case 41% 43% 0.16 -0.03
