Applications of effective field theory methods in nuclear and particle physics

I review recent chiral perturbation theory results for the scalar and vector form factor of the pion in the presence of virtual photons, pion-nucleon scattering inside the Mandelstam triangle, the electromagnetic hyperon and the strange nucleon form factors. Electromagnetic corrections to the energy-momentum tensor of chiral effective field theories are briefly discussed. I also present a precise chiral nucleon-nucleon potential based on a modified Weinberg power counting and discuss the results in the two-nucleon system and their implications.
