how to define invariant mass of the missing part

Asked by panda

Hi
I am trying to define the invariant mass of the missing particle by madanalysis at e+ e- collider since the total enery is known at e+ e- collider and then the invariant mass of the missing particle can be obtained by the visible part.
But seems this observable was not defined in madanalysis5 so how can I define this new observable in the simplest way in madanalysis5.

Hi

MET is defined in normal mode (simply type “plot" and punch tab and you will see all the options). For any other definition you will need to use expert mode.

cheers
