Is there such a thing as an anti-gluon?

  1. Feb 25, 2012 #1
    Since every fundamental particle in the Standard Model should have it's anti-counterpart?

    Also, after the LHC has (if they will ever will) found the Higgs boson, will they start looking for the graviton?

    And please don't mind my username, I can't stand that guy, always talking about fantastical inventions and full of fanciful thinking.

    Michio, Good to hear from you. Gluons are their own antiparticles. Each gluon carries a color and an anti-color. So a particular gluon could be for example, labelled red anti-blue. Its antiparticle would then be another gluon labelled blue anti-red.

    We expect to have enough data by the end of 2012 to tell whether the signal at 125 GeV is really the Higgs boson. Assuming it does, there will be a great amount of work done to study it and determine if it really has all the expected properties. Beyond the Higgs, the LHC will hopefully provide evidence either for or against the existence of supersymmetry at the TeV scale.

    What about gravitons? Must we attempt to prove their existence?

    Also, what is the difference between:

    and

    They represent 2 states in the gluon octet.
