Similarly, for an \textsc{atlas}-like detector, a value of $0.57$ is obtained by \textsc{Delphes} for the $\alpha$ parameter, while the experiment expects it in the range $[0.53~ ;~0.57]$~\citep{bib:ATLASresolution}. 683 684 684 685 \subsection{\texorpdfstring{$\tau$}{\texttau}-jet efficiency} … … 819 820 \bibitem{bib:Delphes} \textsc{Delphes}, \href{http://www.fynu.ucl.ac.be/delphes.html}{www.fynu.ucl.ac.be/delphes.html} 820 821 %hepforge: 821 \bibitem{bib:stdhep} L.A.
