 | Examples of the \EToverPT distribution and fit performed in the $16<\pTtrack<20$~\GeV\ (top), $30<\pTtrack<50$~\GeV\ (middle) and $100<\pTtrack<150$~\GeV\ (bottom) bins in the barrel (left) and endcaps (right). The data are shown by points with a stacked histogram for simulation. The component where $\tau$-leptons decay to multiple charged pions is small and difficult to see. The red fits correspond to simulation and the green fits to data. Both the fits to the full distribution of a Gaussian+Landau function and just the Landau component from this fit are shown. The uncertainties shown are those from the statistics of the dataset and the limited Monte Carlo sample size. The bottom panel shows the ratio of data to simulation with statistical error bars on the data points and a yellow band illustrating the statistical uncertainty of the simulation. The simulation is normalised to the integral of the data. |
