the calculations. My guess is that, though there are massive variations in half-lives with mass, you would still expect a very heavy particle to have a very short half-life. Also, if the Higgs exists and has a long enough half-life to survive to reach a detector, it would surely have shown up by either being detected or sailing through the detector and leaving its indirect imprint in missing momentum. All the really heavy particles detected by accelerators have been detected through their decays.
784:
you didn't want one:-) I don't know the details but I would say the various Higgs bosons (not the
Higgsino, it isn't a boson) are together responsible for the electroweak symmetry-breaking (EWSB) which results in the assigning of mass to particles. It is well-known that EWSB occurs and some of the details are known but there are any number of ways in which you can introduce it into your theory. Hopefully the LHC will help sort out this mess by scouring for bosons in the appropriate mass range.
1068:. So the Higgs boson mean lifetime is between 6.57*10 s and 6.57*10 s. All the reviewer wanted was a qualification of how quickly the Higgs boson decays. I don't want to get into an edit war so I'm not going to make any change myself. But if anyone wants to do the calculation for themselves and put in some helpful qualification at this point, they can. Meanwhile, I shall retire from this discussion and lick my wounds.

accelerating inquiry. Second, it's not a God particle merely because scientists don't like the term. A recent
Economist article pretty well nailed it without being so dismissive outright: "Such power to affect the whole universe has led some to dub the Higgs 'the God particle'. That, it is not. It does not explain creation itself." (The Higgs Boson, Jul 7th 2012 print edition of The Economist).

answer is available then a distinction of fact v. previous theory makes a change to sections sensible, and much of the "theoretical properties" or "alternatives" will be consigned to history too (and best shown in a "historical" section). For now as we don't know and it's all the story of theory, it really does seems to be better in one section as it is.

No longer working on it. Can't find a direct reference to the decay half life of the Higgs. That may not be surprising as it may not even exist and even if it does until it is discovered there may not be enough information to compute the half-life theoretically. Awaiting an expert who knows how to do
688:
The reference to the Higgs being its own antiparticle also implicates electric charge -- antiparticles having equal mass to the original particle but opposite sign of electric charge. Of course, having charge zero you could say it has none of any kind of charge you like but it makes sense to respect
932:
Decided to be bold and fixed this by clarifying that the rapid decay of the Higgs is expected, not necessarily known, because of the decay rates of similarly high mass particles. If this is wrong or the half-life can be theoretically calculated, please amend the article. By comparing with the known
810:
The SM is just the simplest realization of the Higgs mechanism: one SU(2) doublet of complex fields corresponds to four degrees of freedom, three of which are "eaten" by the gauge bosons while the fourth is the physical Higgs boson. However, there is no reason in principle to assume that the Higgs
783:
My understanding is that the multiple Higgs particles are there because the special requirements of the particular extension theory require them in order to be consistent. For example, in the
Minimal Supersymmetric Standard Model (MSSM) you have to have superpartners so you get a Higgsino, even if

I retitled these, but overall I'm still happy to have them in one section. In this article and at this time, the particle itself is still theoretical, the alternatives are theoretical, the background is a discussion of how theory evolved..... the 3 sections read well as a whole. Once a definitive

I would recommend retiring the tiresome and now over-quoted phrase regarding 'God
Particle'--"a name disliked by many scientists." First, 'liking' or 'disliking,' even when scientists are the actors, is completely and absolutely irrelevant requisite for scientific fact, other than detaining or

Fixed. Clarified that electric charge is meant -- as in the diagram, no interaction between photon (the mediator of the electromagnetic force for electrically charged particles) and Higgs. Colour charge, as stated in the relevant article, is a property of quarks and gluons (only) and serves to

SU(2) doublets, in which case the role of the SM Higgs would be played by two combinations of the neutral components of the two doublets, and there would be three more physical fields (one pseudoscalar and two charged). This is e.g. how the Higgs mechanism is realized in the MSSM (because
816:
supersymmetry makes it impossible to give mass to both up-type and down-type fermions with just one Higgs doublet). In summary, I would not say that the additional
Higgses "serve different functions", it's more like the role of the SM Higgs is spread among multiple particles.
883:"The tau lepton is a heavy brethren of the electron. Due to its large mass (approximately 3500 times the mass of the electron) it decays in less than a trillionth of a second after creation into electrons, muons or hadrons (a bunch of quarks)". I found this quote in
890:(SM) is 1.78 GeV and we now expect the SM Higgs to have mass around 125 GeV so you can see it decays pretty fast! I would suggest quoting "less than a trillionth of a second". But I am no expert and would prefer to track down a direct reference. Working on it!
1226:
Unfortunately, retiring phrases isn't really the purview of an encyclopedia as I understand it. If it has actually fallen both out of favor and out of any historical significance with our sources in general because of that economist article, then so be it.

decay rates of the similar mass W and Z particles gave a quantification of what the Higgs decay rate might be. It could vary by several orders of magnitude and still be too rapid to detect.
