\begin{abstract}
The ATLAS $\gamma\gamma$ data is analysied with a simple Breit-Wigner
model. The energy and the width of the Higgs boson is determined.
\end{abstract}
\section{Introduction}
The Breit-Wigner function is given as
\begin{equation}
\label{eq-breit-wigner}
\sigma(E,\Gamma)\propto \frac{1}{(E-E_r)^2+\frac{\Gamma^2}{4}} \,,
\end{equation}
Figure~(\ref{fig-higgs}) shows the fit with the function in
equation~(\ref{eq-breit-wigner}).
