Measurement of sigma (psi(3770) to proton antiproton neutral pion) and determination of sigma (proton antiproton to psi(3770)neutral pion) for the PANDA experiment

The cross section of the decay psi(3770) to proton antiproton and neutral pion has been measured and the cross section of proton antiproton to psi(3770) and neutral pion has been determined. Dector simulation software for the simulation of a time of flight detector upgrade for the BESIII experiement has been developed and tested, as well.The improvement in pion and kaon separation is estiamted.
