distribution of final state neutrinos

Asked by sudesh gupta

Hi
I'm confused with the use of MET (which is sum of neutrino's momemta) class in plot card. I have electron neutrino (ve) in final state of process.

How can I plot delta_phi distribution between MET and jet? and how is it different if I make a new class "neu"

jet 1 -1 2 -2 3 -3 4 -4 21 #class number 1
neu 12 -12 # class number 2
mET 12 -12 14 -14 16 -16 1000022

and then I plot delta_phi between neu class particles and jet.

Thanks

Hi,

I stopped to work with/support that version of MadAnalysis 10 years ago.
So my only real suggestion is to move to MadAnalysis5 which is much more flexible.

This bieng said I do not think that your idea of a new class will work since MET is quite special since you need to sum the 4-momenta of those particle which is not needed for the other class.

Cheers,

Olivier
