transverse mass in Madanalysis
Dear MadAnalysis team:
I generated a process p p > w+ w- by Madgraph. And then I used MadAnalysis to produce MT(w+ w-). Why does the diagram show that all MT(w+ w-) are zero?
If I use this definition:
MT_{w+ w-}^2 = (ET_{w+} + ET{w-})^2 - (PT_{w+}+PT_{w-})^2
, where ET_{w+} = Sqrt(m^
In my situation, PT_(w+) + PT_(w-) = 0. MT_{w+ w-}^2 should be (ET_{w+} + ET{w-})^2 and it is must greater than zero. This result disagree with MadAnalysis' result.
So, how does MadAnalysis deal with the MT? Am I misunderstand the definition about MT(w+ w-)
