We present a complete basis of power suppressed operators for $gg \to H$, classifying all operators which contribute to the amplitude at $\mathcal{O}(\lambda^2)$ and identifying the subset of operators which contribute in the cross section at this order. We show how helicity selection rules significantly simplify the construction of the operator basis. We perform matching calculations to...

The behavior of amplitudes and cross sections in the soft and collinear limits has played an essential role in our understanding of gauge theories. While often studied at leading power in the soft or collinear expansion, the structure of power corrections is of both formal and phenomenological interest. In this talk I will show how techniques from effective field theory can be used to...
