is there a built in cut at the generator level for etmiss?

Hi,

You have the following line in the run_card:
 -1 = missetmax ! maximum missing Et (sum of neutrino's momenta)

As stated this work only for the neutrino.

If you want to add other type of particle,
you can modify the file:
SubProcesses/setcuts.f

and extend the list of covered particle by that cut:
c-neutrino's for missing et
         if (abs(idup(i,1,iproc)).eq.12) is_a_nu(i)=.true. ! no cuts on ve ve~
         if (abs(idup(i,1,iproc)).eq.14) is_a_nu(i)=.true. ! no cuts on vm vm~
         if (abs(idup(i,1,iproc)).eq.16) is_a_nu(i)=.true. ! no cuts on vt vt~

Cheers,

Olivier
