If a detection is widely contested, I will use my (somewhat conservative) discretion. In the event of no detection by close time, this will resolve to MKT.
Any mass outside the range will just resolve to the appropriate limit.
The rough masses of various standard model particles:
0: photon, graviton (as far as we know)
< .12 eV: neutrino
500 KeV: electron
1 GeV: proton, neutron
125 GeV: Higgs
173 GeV: top quark (heaviest SM field)
Miscellaneous clarifications (all the rules about resolution that I think are unlikely, but I'd like to specify in advance to avoid people getting upset).
If two or more detections are announced simultaneously, I'll take the geometric mean of their masses. Particles that are massless get treated as 1eV in this procedure, just as they would be if detected alone.
