We perform a study of the Standard Model (SM) fit to the mixing quantities Delta M_{B_s} and Delta Gamma_{B_s}/Delta M_{B_s} in order to bound contributions of New Physics (NP) to B_s mixing. We then use this to explore the branching fraction of B_s -> mu+mu- in certain models of NP. In most cases, this constrains NP amplitudes for B_s -> mu+mu- to lie below the SM component.
