Applying a cut on E_T^miss in the run_card.dat

Asked by shibasipu

Dear Olivier,
                           I want to apply a cut on MET in the run_card.dat. In this case, the source of MET is due to presence of some dark matter candidates in the final states not due to the NEUTRINOS. But in the run card, it is mentioned you can apply cuts for neutrinos. i.e.

0.0 = misset ! minimum missing Et (sum of neutrino's momenta)

Can I use the above thread in the run_card.dat to apply cut on MET ( presence of some dark matter candidates in the final states not due to the NEUTRINOS) ?

Regards,
Shiba

Dear Shiba,

For that you need to specify the DM as a neutrino for the cut point of view

in SubProcesses/setcuts.f you have the following lines:

         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~

You can add the corresponding line for your DM and then using the entry in the run_card should work.

Cheers,

Olivier
