PHOTOS Monte Carlo is widely used for simulating QED effects in decay of intermediate particles and resonances.It can be easily connected to other main process generators.In this paper we consider decaying processes γ*→π+π-(γ)and K±→π+π-e±ν(γ)in the framework of Scalar QED.These two processes are interesting not only for the technical aspect of PHOTOS Monte Carlo,but also for precision measurement ofαQED(Mz),g-2,as well as ππ scattering lengths.
