The neutral pion Ï0 is a combination of an up quark with an anti-up quark or a down quark with an anti-down quark. The two combinations have identical quantum numbers, and hence they are only found in superpositions.The lowest-energy superposition of these is the Ï0, which is its own antiparticle.Together, the pions form a triplet of isospin. Each pion has isospin (I = 1) and third-component isospin equal to its charge (I z = +1, 0 or â1).he ÏÂ± mesons have a mass of 7002139600000000000â 139.6 MeV/c2 and a mean lifetime of 6992260000000000000â 2.6Ã10â8 s. They decay due to the weak interaction. The primary decay mode of a pion, with probability 0.999877, is a purely leptonic decay into an anti-muon and a muon neutrino :
