M_{eff}
 hepph/9610544[1], hepph/0006276[2]
 Discovery of New Physics with massive particles.
 Bad, quoted to be 20%50% in references, but needs to be interpreted in a specific model.
 Discovery above SM contribution and estimating mass scale of particles with dominant cross section.
 Does not identify process, but gives some information on particle content of dominant topologies.

H_{T}

 always


 does not identify process in any way
