abstract
Using the hierarchy of scales between the mass, $M$, and the width, $\Gamma$, of a heavy, unstable particle we construct an effective theory that allows calculations for resonant processes to be systematically expanded in powers of the coupling $\alpha$ and $\Gamma/M$. We illustrate the method by computing the next-to-leading order line shape of a scalar resonance in an abelian gauge-Yukawa model.

Super-resonant dark matter at O(100) GeV masses amplifies self-scattering and annihilation cross sections via combined resonance and Sommerfeld effects, necessitating coupled Boltzmann equations to match observed relic density.
Non-factorisable two-loop EW virtual corrections to single-resonant processes reduce to an iteration of the one-loop result plus a new light-fermion contribution in dimensional regularization and are specific to single-resonance exchange.
