Pions that decay give rise to the muon and neutrino components which easily penetrate the atmosphere. Although the mean life of muons at rest is short, approximately 2.2·10 −6 s, the majority survives down to sea level because of time dilation. However, …

The WZW vertex factor can be obtained by introducing the Fourier transform of each field in. iSWZW = i.

The rare double Dalitz decay of the neutral pion proceeds through a two-photon intermediate state, pi0 → gamma*gamma* → e+e- e+e-, which provides sensitivity to the physics of the pi0gamma*gamma* coupling. The properties of this interaction are a consequence of the internal structure of mesons in general.

2 Pion decay widths of the D mesons 2.1 Single quark approximation The main contribution to the decay widths of the D mesons in the ground state band is due to the pion decays D ! Dˇ.These transitions are intriguing in that since the mass di erence MD − MD is very close to the pion mass, the available phase space is very small.

This offers a  The dominant decay of a neutral pion is the electromagnetic decay in two photons: BF = 98.8 percent. Sideremark: Since the decay into three photons is not  decaying after a much shorter lifetime of 84 attoseconds (8.4×10−17 seconds). Charged pions most often decay into muons  A pion (mass Mp) decays into a muon (mass Mμ) and a neutrino (massless). (a) Find the kinetic energy of the muon in the rest frame of the pion.
