\begin{columns}
\column{2.5in}
\begin{itemize}
\item Drell-Yan are process of two quark anihilations in which neutral coupling to two leptons.
\item The cross section of this process depends on two components:
\begin{itemize}
\item Hard scattering process $\color{OrangeRed}{\Rrightarrow}$ NNLO pQCD.
\item Parton Distribution Function (PDF).
\end{itemize}
\item Measurement of the cross section have a high sensitivity to the PDF
\item Due to unique coverage $2<y<5$ LHCb probes the $Q^2-x$ region not covered by other experiments.

\end{itemize}

\begin{frame}\frametitle{Isolation}
\begin{itemize}
e\item Drell-Yan unfortunately do not peak in mass $\twoheadrightarrow$ need another variable to control the purity.
\item Instead we define an isolation variable:
\begin{align*}
\mu_{ {\rm{iso}}} = \log(p_T^{ cone}(\mu, 0.5) - p_T^{ cone}(\mu, 0.1))
\end{align*}
\item For two muons we take the maximum of the two isolations:
\begin{align*}
\mu\mu_{ {\rm{iso}}} = \max( \mu_{ {\rm{iso}}}^+, \mu_{ {\rm{iso}}}^-)
\end{align*}

\begin{itemize}
\item We reprocess the data and the new MC with S20.
\item A lot of consistence checks done between 2011 and 2012.
\item The final fits converge in similar manner for 2011 and 2012 data sets.
\item Started writing the \texttt{ANA} note.
\item There is one thing I am trying out: So up to now I was using the \texttt{TFractionFitter}, there is a RooStats/RooFit fitter: \texttt{HistFactory}
