How to select SFOS lepton pairs in Madanalysis?

Asked by Melissa

Dear reader,

I could not find how to select same-flavor opposite-sign lepton pairs in Madanalysis and use these to e.g. plot invariant mass of the two. Is there a way?

Cheers,
Melissa

Hi Melissa,

You can simply request that the number of l+l- pairs that can be formed must be greater than 1:
  select N(l+ l-)>=1
For the invariant mass, this is as easy:
  plot M(l+ l-)

Regards,

Benjamin
