The as yet undiscovered spin singlet D ∗ 1 state is predicted to have a larger width of 7- 10 MeV for ππ decay. We study the behavior of the $\pi^0$ width as a function of temperature and density.

Away from these limits some corrections from QCD are expected. The recent PrimEx experiment at JLab has measured the neutral pion decay width to an accuracy of 2.8% [6]. The next stage of this experiment is to achieve a precision of 1.4%.

decay of both the muon and the tau, a virtual charged intermediate vector boson (W*) materializes into fermion-antifermion pairs. Because the mass of the muon is less than that of the lightest meson (the pion), the muon cannot decay to final states containing hadrons. We give a rather self-contained introduction to the rare pion to dielectron decay which in nontrivial leading order is given by a QED triangle loop.
