[QUOTE="Umbran, post: 5885875, member: 177"] I thought there was weirdness there, so maybe I'm half-remembering correctly. Fine, let's simplify. The gauge bosons are all weird anyway - either they have the W/Z odd couplings, or they are zero mass. So, let's use a meson - a composite boson, not a quasiparticle. My recollection is that the math works out such that annihilation is still less likely for the meson than for fermions of similar mass and charge. We can even compare here, those mesons which are their own antiparticle (like a charmed eta), with ones that aren't (say, a Pi+). Do you know offhand how the math works out for those? I admit I don't. [/QUOTE]
