The rapidity spectrum for gluon fusion Higgs production is an important observable in upcoming precision measurements at the LHC. It also enters measurements of the production cross section through the fiducial acceptance. On the theory side, perturbative corrections to the spectrum contain large logarithms that can be resummed to all orders. We show how their resummation can be performed by RG evolution in a SCET-based framework, leading to the currently most precise predictions for the Higgs rapidity spectrum. Our formalism also applies to other color-singlet production processes.
