Particle physics

1) The anti-meson of pi+ is pi-, does pi0 have an anti meson?
2) Can anyone name an anti-lepton apart from a positron?

the pi 0 consists of an up and an anti-up quark or a down and an antidown quark. The 'antiparticle' versions are simply these quarks the other way round (i.e. they are their own antiparticles).

Other leptons are muons and taus. These leptons do not have "named" antiparticles like the electron has the positron, they are simply called the anti-muon and anti-tau.

There are also neutrinos which are leptons - the electron neutrino, muon neutrino, tau neutrino. The antiparticle versions of these are just called 'electron anti-neutrino', etc.

Hope this helps. Any more questions just ask.
