This is the symbol...

enter image description here

It's like a uppercase and cursive l.

    Quick tip: you can use http://detexify.kirelabs.org/classify.html to look up symbols, which in this case leads to \usepackage{mathrsfs} and \mathscr{L}. – Torbjørn T. Apr 05 '15 at 22:27
  • As the comment @TorbjørnT. should solve it, I closed as a duplicate to the general approach question. So later people are lead to that one, instead of having 1000 answers, one per question for each possible symbol. ;-) – Stefan Kottwitz Apr 05 '15 at 22:31
  • @cursolloonline: it is very close to the boondox font, for which there is a package on CTAN – Bernard Apr 05 '15 at 22:43

It is very close to the boondox calligraphic font:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}

\usepackage{boondox-cal}

\pagestyle{empty}

\begin{document}%

$ \begin{array}[t]{c@{\quad}c}
\multicolumn{2}{l}{\mathbf{Boondox:}}\\
\verb+ \mathcal + & \verb+ \mathbcal + \\[6pt]
     \mathcal{L l} & \mathbcal{L l}
    \end{array} $

\end{document}
