Has the Higgs Boson Particle Field Been Hiding in Plain Sight? 163
sciencehabit writes with a link to the ScienceNow site, noting an article saying the Higgs boson may already have been found in previous observations of the known universe. A theorist at Michigan state is arguing that scientists may have already found evidence for the elusive particle. The key appears to be that the particles that make up the Higgs field are of various 'strengths', and some of those particles may tug on others very weakly. "The lightest Higgs can be very light indeed, but it would not have been seen at [CERN's Large Electron-Positron (LEP)], because LEP experimenters were looking for an energetic collision that made a Z that then spit out a Higgs. That wouldn't happen very often if the lightest Higgs and the Z hardly interact. 'Just within the simplest supersymmetric model, there's still room for Higgs that is missed,' Yuan says. However, this lightweight Higgs is not exactly the Higgs everyone is looking for, says Marcela Carena, a theorist at Fermilab. 'The Higgs they are talking about is not the one responsible for giving mass to the W and Z,' she says. It can't be because it hardly interacts with those particles, Carena says. Indeed, in Yuan's model, the role of mass-giver falls to one of the heavier Higgses, which is still heavier than the LEP limit, she notes."

It is the only Standard Model particle not yet observed, but would help explain how otherwise
massless elementary particles, still manage to construct mass in matter. In particular, the difference between the massless photon and the relatively massive W and Z bosons
I always wondered what they use to measure the mass of elementary particles (not atoms). Can anyone explain? Also, maybe photons and higgs boson do have mass, but our instruments just aren't sensitive enough (kinda what the summary is saying)?

You get a negative energy.
This is actually possible near the event horizon of a spinning blackhole. The zero energy state around a spinning blackhole is a particular orbit (I believe due to frame dragging, but I'm not positive), but a slower orbit must have lower energy which thus must be negative energy. The Penrose process uses this trick to extract energy from a blackhole.
