Description
Summary:FASTERD is a Monte Carlo event generator to study the final state radiation both in the e@u+e@u-- > p@u+p@u-g and e@u+e@u-- > p@u0p@u0g processes in the energy region of the f-factory DAFNE. Differential spectra that include both initial and final state radiation and the interference between them are produced. Three different mechanisms for the ppg final state are considered: Bremsstrahlung process (both in the framework of sQED and Resonance Perturbation Theory), the f direct decay (e@u+e@u-- > f- > (f@d0;f@d0+s)g- > ppg) and the double resonance mechanism (as e@u+e@u-- > f- > r@u+/-p@u?- > p@u+p@u-g and e@u+e@u-- > r- > wp@u0- > p@u0p@u0g). Additional models can be incorporated as well.
