Overview of chiral predictions for neutral pion photo-/electroproduction
off protons, neutrons and deuterons

Theoretische Physik T39, TU Muenchen
I will present an overview on recent calculations in chiral effective field
theories regarding the low energy behaviour of neutral pion
photo-/electroproduction off protons [1], neutrons [2] and deuterons [3]. I
will
also discuss the role of explicit Delta(1232) degrees of freedom [4] for some
of
these processes.
