- Possible, but *extremely* unlikely. Basically *all* experimental
- evidence points toward confinement; there are only a handful of
- experiments that seem to indicate free quarks, but so far none of
- these have been repeated.
-
- And as a QCD theorist, I strongly object to the word "conjecture"
- above; even though it's not been proved yet, confinement is _much_
- more than mere conjecture.
-
- What is more interesting is the possibility of having charged,
- meta-stable particles of more exotic kinds, such as "strangelets"
- (colour-neutral lumps of large number of s quarks), supersymmetric
- particles, and so on.
-
- The word meta-stable means that the particles don't really have to be
- stable to catalyze fusion. I don't know the latest status of
- muon-catalyzed fusion, but muons may be just long-lived enought to do
- it.
