\begin{itemize}
\item LHCb cover a very unique region of the phase space that is not accessible for any other experiments.
\item One could measure in this regime:
\begin{itemize}
\item $\PW$, $\PZ$ cross section.
\item Drell-Yan cross section.
\end{itemize}
\item These measurements would strongly constrain the PDF in the fits.
\end{itemize}


\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}\frametitle{Cross section}
$\Rrightarrow$ Higher energy $\Rightarrow$ Higher cross section:
\includegraphics[width=0.95\textwidth]{images/xsection.png}

$\Rrightarrow$ In contrast to RD the EW measurements should start much sooner as they are not statistically dominated!


\end{frame}

\begin{frame}\frametitle{What could we do?}

$\Rrightarrow$ For starters we should start by measurement of $\PZ$ cross section (already ongoing in the group).\\
$\Rightarrow$ Relativity simple, you don't need much data.\\
$\Rightarrow$ Important for MC tuning.\\
$\Rrightarrow$ More interesting: Tripple Gauge Boson Couplings:\\{~}\\

\begin{itemize}
\item Clear SM prediction.
\item Sensitive to anomalous couplings!
\item ATLAS observed a small but consistent deviation in this measurement.

\column{0.45\textwidth}
\begin{itemize}
\item Very clean theoretical prediction!
\item Effectively you are probing the proton PDF. 
\item Remember that the theory error for all the Higgs calculations comes from PDFs.
\item One could improve really the PDFs thanks to special kinematic region of LHCb.
\item We could reach lower $x$ region of $10^{-6}$, trigger is there! Background needs to be understood.

\begin{itemize}
\item Super clean theoretically.
\item Signature: protons interact and go to the beam pipe undetected, in the detector you are left with couple of particles.
\item Probing PDF and also thanks to DPE we have a link to Higgs Physics.
\item Getting sensitive to saturation effects?

\item They cover $5<\eta<8$.
\item Rejecting the main background for CEP.
\item Allows to measure $p_T^2$ distribution for inelastic events.
\item Dedicated \texttt{L0} trigger for CEP.

\begin{frame}\frametitle{top physics}
\begin{itemize}
\item Katharina already presented our recent measurement of top measurement in the forward region.
\item with Run2 data ($5~\rm fb^{-1}$):
\begin{itemize}
\item $[\Plepton, \Pbeauty]$: expect $\sim$  $8300~\Ptop \APtop$ , $5000~\Ptop$-channel, $600~\Pstrange$ -channel, and $180~\PW \Ptop$.
\item $[ \Plepton, \Plepton , \Pbeauty, \Pbeauty]$: expect $\sim$ $530~\Ptop \APtop$.

\begin{columns}
\column{0.05\textwidth}

\column{0.5\textwidth}
\begin{itemize}
\item One can measure the $A_{FB}$ in the $\PZ \to \Pmu \Pmu$ decays:
\begin{align*}
A_{FB}=\dfrac{\sigma(\cos \theta >0) - \sigma(\cos \theta <0) }{\sigma(\cos \theta >0) + \sigma(\cos \theta <0) }
\end{align*}
\item This is dependent on the vector and axial couplings $\Rightarrow$ $\sin \theta_W^{eff}$.
\item Since LEP time there is a small tension in this measurement.
\item With full Run2 data and some smart ideas we might be close to LEP!
\item ATLAS and CMS will not not be able to compete.
