The reaction is observed in a … We compute the decay rate of dimuonium into a neutral pion and a photon. We find that approximately one in 105 ortho-dimuonia decays into this channel. We also determine the contribution of the virtual photon-pion loop to the hyperfine splitting in dimuonium and reproduce its leading effect in the anomalous magnetic moment of the muon. Photons decay into positrons and pions, and pions are mesons which decay into one quark and one antiquark, while positrons are the antiparticle (antimatter) equivalent of the electron. Quarks eventually become hadrons, so baryons or mesons. The pion, one of the two particles photons decay into, is a meson.

but using conservation of energy E(pion) = E(photon1) + E(photon2) doesnt seem to help because although we now have E(pion) the energies of each photon may not be equal. also how would you calculate momentum without a velocity? Example: pi meson decay A pion has a rest energy of 135MeV. It decays into two gamma rays (photons).

The first lower limit on τ π 0 came from measurements of K + 2π decay at rest in nuclear emulsions, where K + →π + π 0 was followed by the Dalitz decay of the π 0 , π 0 → e + e − γ. We perform non-perturbative calculation of the \\pi^0 to {\\gamma}{\\gamma} transition form factor and the associated decay width using lattice QCD. The amplitude for two-photon final state, which is not an eigenstate of QCD, is extracted through an Euclidean time integral of the relevant three-point function. We utilize the all-to-all quark propagator technique to carry out this integral as 1991-01-31 · The pion decay rate into two photons obtained with the contribution of the anomaly in the axial current fits the corresponding experimental number very well and is one of the proofs in favor of the fact that three colors of quarks exist.
