Electroweak penguin decays at LHCb

Promising ways to search for New Physics effects in radiative penguin decays are in the angular analysis of $B_{d} \rightarrow K^{*0} \mu^{+}\mu^{-}$, in the measurement of direct CP violation in $\B_{d} \rightarrow K^{*0}\mu^{+}\mu^{-}$ and a time dependent analysis of $B_{s} \rightarrow \phi \gamma$. All of these studies are being pursued at LHCb. First results will be shown from the 2010 and early 2011 data, with particular emphasis on $B_{d} \rightarrow K^{*0} \mu^{+}\mu^{-}$.
