Description
In this talk I will summarize the theory and phenomenology status of the inclusive penguin decay $B \to X_s \ell \ell$. In the high-$q^2$ (soft recoil) region above the narrow charmonium resonances, the inclusive rate is dominated by two exclusive modes $B \to K^{(*)}\ell \ell$. I will explain that this property of the spectrum provides an opportunity to apply the toolkit of inclusive B decays to results from LHCb as well as the B factories. I will also present a study of the hadronic mass cut dependence of the rate and forward backward asymmetry at low-$q^2$, and discuss different strategies for normalizing the neutral-current decay to charged-current B decays.
