2 Charged pion decay The main decays of the charged pion are leptonic ˇ ! e e; ˇ! In all that follows, the charged conjugate decays, i.e. here ˇ+! e+ e, etc, are also implied. This decay requires the quarks, e.g. du in the case of a ˇ , to have annihilated each other as there are (by de nition for a leptonic decay…

This prediction is remarkable because it contains no unknown low-energy constants or form factors and is in agreement with the currently accepted value for the radiative width, 7.74±0.46 eV ( 2 ), which confirms N C = 3 as the number of QCD colors. 2017-06-10 OSTI.GOV Journal Article: Neutral Pion decay width in a hot and dense medium.
