- \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.

- \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}}}^-)

- \item There are two sources of backgrounds:
- \begin{itemize}
- \item Heavy flavour decays.
- \item Mis-ID.
- \end{itemize}
- \item For fitting the $\mu\mu_{iso}$ we need to know both the signal and background distribution.
- \item Background templates can be determined from data
- \begin{itemize}
- \item Heavy flavour decays:\\
- $\looparrowright$ Requiring the $\chi^{2,\mu\mu}_{vtx}>16$\\
- $\looparrowright$ For cross-check $\rm IP>5~\rm mm$
- \item Miss-ID:\\
- $\looparrowright$ Require that both muons have the same sign.\\
- $\looparrowright$ For cross-check take the minimum bias stripping line.

- \item We do not want to use MC for determination of the signal $\mu\mu_{iso}$ template.
- \item We adopted a data driven procedure:
- \begin{itemize}
- \item The template is taken from data and scaled to account for $\mu\mu_{iso}$ mass dependence.
- \end{itemize}
- \item Possibility 1:
- \begin{itemize}
- \item Take the \textit{Splot} $\PZ \to \mu \mu$ from data and multiply it by the scale factor determined from minimalising the $\chi^2$ between MC $\PZ$ and DY in particular region.

- \item Possibility 2:
- \begin{itemize}
- \item Use a second decay from data: $\PUpsilon \to \mu \mu$.
- \item The template for a given mass range ($M_{\min}, M_{\max}$) is choose as:
- \begin{align*}
- {\rm{Temp}}(M) = \\ {\rm{Temp}}^{\PUpsilon} \frac{(M_{\PZ} -M_{\PUpsilon} - (M- M_{\PUpsilon} ))}{M_{\PZ} -M_{\PUpsilon}}\\ + {\rm{Temp}}^{\PZ} \frac{M- M_{\PUpsilon} }{M_{\PZ} -M_{\PUpsilon}}

- \item Possibility 3:
- \begin{itemize}
- \item The one problem with this distributions is that the first bin is insensitive to scaling factors.
- \item On top of the previously defined template we define an additional scaling factor that modifies the ratio between the first and the rest of the bins.

- \begin{itemize}
- \item We are investigating the impact on the analysis for the different approaches
- \item For now it looks like the results are within the statistical error of the fits.
- \item The reason for this that in the high pseudo-rapidity region $4<y<4.5$ there is very small number of $\PZ$ decays, so the additional $\PUpsilon$ decays are helping.
- \item We are considering constrainting the background shape in the fits (we know background is exponential in mass).
