Momentum analysis of kaon and pion pairs produced from time-like photons at 1.6 GeV energy
Abstract
We present results for the total cross section of e+e- annihilation into two hadrons at 1.6 GeV: σππ = σKK = (1.8 +/- 1.1) × 10-33 cm2.From these values we obtain the time-like electromagnetic form factors these mesons: Fπ2 = 0.24 +/- 0.14 and FK2 = 0.46 +/- 0.26.
