Scientific paper

The complex-mass scheme (CMS) provides a consistent framework for dealing
with unstable particles in quantum field theory and has been successfully
applied to various loop calculations. As applications of the CMS in chiral
effective field theory we consider the form factor of the pion in the time-like
region and the magnetic moment of the Roper resonance.
