problem in cut implementation

Asked by nabanita ganguly

Hi,
I am working with a .lhco file generated by MG5 . I want to plot the variable dETA and employ a cut on it. SO I did the following :

plot dETA(j[1] j[2])
reject -2 < dETA(j[1] j[2]) < 2
The cut table shows reduction in events
Then to make sure that the cut has been implemented correctly I again plot dETA(j[1] j[2]).
But the plot is showing events between (-2,2). that definitely means cut has not been applied properly. Could you please suggest why is that happening?What is the proper way of implementing this cut then?

I try with other kinematic variables like M(j[1] j[2]) DELTAR(j[1] j[2]). No such inconsistency is coming there.

Regards,
Nabanita
