Signal separation from background

Characteristics difference of a single muon and a muon bundle was investigated in ordert to separate signals from backgrounds.

Remarks

Mean value of the time residuals for signal and background gets closer, compared to the case for the MC true. This may means that we can use this parameter to express the distance for any flavor except nue...
On the other hand, the spread is quite different. So, the difference can be used for the descrimination...
