Is fission or fusion of antiparticles possible?

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:
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
