We re-examine the kinematic variable mT2 and its relatives in the light of recent work by Cheng and Han. Their proof that mT2 admits an equivalent, but implicit, definition as the ‘boundary of the region of parent and daughter masses that is kinematically consistent with the event hypothesis’ is far-reaching in its consequences. We generalize their result both to simpler cases (mT , the transverse mass) and to more complex cases (mTGen). We further note that it is possible to re-cast many… CONTINUE READING
