requiring two unique pairs of opposite sign same flavor leptons which reconstruct Z boson

Hi Prudhvi,

Would cuts on the leading and next-to-leading guys do the job, like for instance replacing your conditions by something like
select 71.2 < M(e[1] e[2]) < 11.2

Another option would be to use the expert mode.

Regards,

Benjamin
