Recently the LHCb collaboration announced a $2.6 \\sigma$ deviation in the measurement of $R_K={\\cal{B}}(\\bar B \\to \\bar K \\mu \\mu)/{\\cal{B}}(\\bar B \\to \\bar K ee)$ from the standard model's prediction of lepton universality. We identify dimension six operators which could explain this deviation and study constraints from other measurements.
