Simulation and Analysis of the channel p p → e+e−π0 using the TDA production mechanism for its measurement with PANDA. — •María Carmen Mora Espí, Manuel Zambrana, and Frank Maas for the PANDA collaboration — Helmholtz-Institut Mainz, Mainz, Deutschland
The Transition Distribution Amplitudes (TDA) are universal non-perturbative objects describing the transition between two different particles. The TDA production mechanism can be used in the factorised description of hard processes which can be produced in PANDA at FAIR. One of these processes is the proton-antiproton annihilation into a lepton pair with high invariant mass q2 in association with a neutral pion of low transverse momentum, p p → e+e−π0. Detailed simulation studies for the measurement of this channel have been performed including the separation of the signal channel from its main background channel (p p → π+π−π0) as well as the study of the reconstruction efficiency of the signal. The preliminary results and the first conclusions are presented here together with a short discussion over the possible access of the TDA with PANDA.
