selecting same-flavor leptons

Asked by Aielet Efrati

Hi,

I want to reject all events which do not have a pair of same-flavor leptons.
I'm trying to do $reject N(mu or e)<2$, but it's not working

How should I define this cut?

Thanks
Aielet

Dear Aielet,

What you are trying is indeed wrong, syntax-wise. You can instead try the following:
define mu = mu+ mu-
define e = e+ e-
select N(mu)>=2 or N(e)>=2
This will select all events that have either at least two electrons/positrons, or at least two muons/antimuons.

Cheers,

Benjamin
