Notes:
H and W are short-lived.
Look for accomplices—"daughter" or "granddaughter" particles.
(Note example of data on the right.)
H may decay to 2 b quarks which fragment into 2 B mesons which decay quickly into lots of particles.
Look for jet of particles coming from same point for a B.
W may decay into electron and neutrino or muon and neutrino.
(Neutrinos are "stealth" particles with really light mass. Aren't seen in CDF.
Computers calculate "missing neutrino momentum"; indicated with red arrow.)
