Top quark and matter-antimatter

    up quark and down quark

    An up quark has a smaller mass than a down quark.
    Is it possible that an up quark is made from 2 antidowns with energy being released?

    Composite models, techicolor, topcolor etc. It is assumed that the top quark is a condensate of some other particle (not other quark). A lot of work done. No idea about how it relates to matter/antimatter symmetry (antimatter is always likely to anhiquilate against matter).

    So two colour charges can't come together and form one colour charge
    by releasing some energy that carries a second colour charge?

    well, quarks are not only defined by colour, also electric charge and weak isospin. So another kind of particle is required. This is called techicolor.

    An up Quark has more fractional Charge than a Down Quark..
    UP 2/3 charge Down 1/3 Charge

    2/3..'two thirds' of a down composite Quark..does not equal..2/3s of an Up Quark.

    Matter prevails over Anti-Matter..there are I believe experiments underway at CERN:http://www.exploratorium.edu/origins/cern/ideas/antimatter.html
    which are hoping to uncover if the 1/3 fractional charge of ordinary Protons, represents 'Negative' matter, and it may be that the Anti-Matter Anhilations, will show this to be so?

    For instance the Matter >>Antimatter anhilation spectrum, might reveal the energy released to be 'less or more' than the reversed interaction of Anti-Matter .>> Matter interactions.

    The fact that fractional charge has the configuration it has 1/3 + 2/3..is a remnant of early Universe interaction..it does not balance out..for instance if Quarks had a Fractional Charge of 1/4 +1/4..this would be perfectly symmetrical..and matter could not prevail over Anti-Matter?
