Angle of etmiss in MadAnalysis

Asked by Nick

I would like to apply a cut in MadAnalysis that requires that the distance between the distance of etmiss and the 2nd leading jet are greater than some value (as is done in ATLAS monojet cuts). My problem is I am not sure how to access the angle or 4-vector components of the combined etmiss. I know I could use dRij to limit the distance between a jet and any one particle in the class mET, but this is not what I am interested in.

I did find that there is a variable called pmiss in plot_events.f (lines 230-240), so perhaps I could use this variable, along with dRij, in a user-defined function in kin_func.f? If so, I am not sure what the proper syntax is to access it (something similar to what is done here: https://answers.launchpad.net/madgraph5/+question/208568 ??). If not, is there another way to go about solving my problem?

Hi Nick,

Did you look to MadAnalysis5 (http://madanalysis.irmp.ucl.ac.be/).
 It might be more suitable for this.
And this is fully documented on how to add new type of cut.

Cheers,

Olivier
