Pion Photo- and Electroproduction with ChiralMAID

Lothar Tiator (Mainz)

I present a calculation of pion photo- and electroproduction on the nucleon in manifestly Lorentz-invariant baryon chiral perturbation theory up to and including chiral order p4.  Within this framework we analyzed all available π0 and charged photo- and electroproduction data in the threshold region.  We could show that chiral perturbation theory in p4 can consistently describe all pion photo- and electroproduction processes in the threshold region equally well.  I will further discuss the validity of the chiral approach away from threshold.  First this depends on the energy and virtuality of the photon, but secondly also very heavily on the charge of the produced pion.  This relativistic chiral perturbation theory calculation is now available within the MAID project as ChiralMaid under
