+\section{The \LHC}
+The Large Hadron Collider (\LHC) at \CERN is a new hadron collider,
+located in the same tunnel as the Large Electron-Positron collider
+(\LEP)~\cite{Brianti:2004qq}. Where \LEP's chief task was the use
+of \unit{90--207}{\GeV} \epluseminus collisions to establish the
+precision physics of electroweak unification\dots

+\section{The \LHCb experiment}
+\label{sec:LHCbInDetail}
+
+Since both \bhadron{s} are preferentially produced in the same direction
+and are forward-boosted along the beam-pipe, the detector is not required
+to have full $4\pi$ solid-angle coverage. \LHCb takes advantage of this
+by using a wedge-shaped single-arm detector with angular acceptance
+\unit{10-300}{\mrad} in the horizontal (bending) plane~\cite{Amato:1998xt}.

+
+The detector is illustrated in \FigureRef{fig:LHCbCrossSection}, showing
+the overall scale of the experiment and the surrounding cavern structure.

+ \label{fig:LHCbCrossSection}
+ \end{center}
+\end{sidewaysfigure}
+
+The single-sided detector design was chosen in preference to a two-armed
+design since the detector dimensions are restricted by the layout of the
+IP8 (ex-Delphi) cavern in which \LHCb is located. Using all the available
+space for a single-arm spectrometer more than compensates in performance
+for the \about{50\percent} drop in luminosity.
+
+\section{The \Cerenkov mechanism}
+A Huygens construction in terms of spherical shells of probability for photon
+emission as the particle progresses along its track shows an effective
+``shock-front'' of \Cerenkov emission. This corresponds to an emission cone of
+opening angle \thetaCerenkov around the momentum vector for each point on the
+track,
+%
+\begin{subequations}
+ \label{eq:cosThetaCk}
+ \begin{equation}
+ \cos\,\thetaCerenkov &= \frac{1}{n \beta} +
+ \frac{\hbar k}{2p}%
+ \parenths{ 1 - \frac{1}{n^2} } \\
+ &\,\sim \frac{1}{n \beta}%
+ \label{eq:cosThetaCkApprox}
+ \end{equation}
+\end{subequations}
+%
+where $\beta \equiv v/c$, the relativistic velocity fraction.

+is shown in \Table~\ref{tab:TriggerDetails}.
