Incorrect transverse mass `mt2` definition

idk why we didn't do the naive px^2 + py^2
, because that seems to be correct
here our mt^2
is effectively
E^2 - pz^2 = m^2 + px^2 + py^2 + pz^2 - pz^2
which only gives me correct plot if particle is massless
but it's how ROOT does it https://root.cern.ch/doc/master/TLorentzVector_8h_source.html#l00513
@aminnj halp
I think we're missing a 2-particle version of mt2
and mt
because that's apparently different from mt(vec1 + vec2)
, makes sense
