    That terminology is not very helpful in particle physics. In nuclear reactions the fundamental entities you are dealing with don't change (except for a beta decay here and there...) while in fundamental interaction you often end up with entirely different final states than you started with. People throw the words around (for example there is gluon fusion, in which two gluons collide and produce say a Z or something, which then decays into other stuff) but it is more in the spirit of the ordinary meaning of the word rather than out of any particularly strong analogy with nuclear interactions.

    Yes, but it is a bit pointless because you can get far more energy from combining it with matter.

    They are both as 'real' as anything particle wise. When they meet they don't 'disappear', leaving no trace of their existence. They annihilate into 'real' radiation. So you can do anything with a anti particle that you can do with a particle, as far as I know they are a sort of 'mirror symmetry', not 'negative' as in 'disappearing' into a 'nothing'.

    ok. thanks guys.

    Except perhaps with beta decay. :biggrin:
