In case you do not have it yet, please download the package form the internet and install it in our subdirectory. The text of your manuscript should be produced using two-column format, within the dimensions shown on these pages: total width of 17.5~cm and a maximum length of 24~cm on each page. The \LaTeX{} document class uses the maximum stipulated length apart from the following two exceptions (i) \LaTeX{} does not begin a new section directly at the bottom of a page, but transfers the heading to the top of the next page; (ii) \LaTeX{} never (well, hardly ever) exceeds the length of the text area in order to complete a section of text or a paragraph. Some examples of references are given as in Ref. \cite{HBT,GGLP} and in \cite{purcell}-\cite{WeinerBook}. \subsection{Spacing} We normally recommend the use of 1.0 (single) line spacing. However, when typing complicated mathematical text \LaTeX{} automatically increases the space between text lines in order to prevent sub- and superscript fonts overlapping one another and making your printed matter illegible. \subsection{Fonts} These instructions have been produced using 11 point Times fonts, normally used by {\bf RevTeX 4} document class. Don't use too small fonts to guarantee legibility. %\section{TABLES AND ILLUSTRATIONS} \section{TABLES} Tables should be made with \LaTeX; illustrations should be originals or sharp prints. All the captions should be clearly legible. They should be arranged throughout the text and preferably be included {\em on the same page as they are first discussed}. They should have a self-contained caption and be aligned in the center of the text. \subsection{Examples} Tables should be presented in the form shown in Table~\ref{tab1} (when an intermediate line through all the table is necessary) or Table~\ref{tab2}. They also illustrate cases with different number of columns. Their layout should be consistent throughout the text, so please use these models adapted to your contents. \begin{table}[htb] \begin{center} \caption{\bf Table format with an intermediate line throughout it} \begin{tabular}{|c|c|c|} %\hline\hline \hline % & & \\ $\chi^2(R_{T},\Delta \tau)$ & No Resonances & LUND Resonances \\ % & & \\ \hline\hline \multicolumn{3}{|c|}{ Comaparing Data to Model - 2 scenarios}\\ \hline\hline $|\chi^{2}_{min}-1|/\sigma$ & 2.1 & 2.2 \\ \hline $R_{0_T}$ & 4.6$\pm$ 0.9 & 3.1$\pm$ 1.3 \\ \hline $\Delta\tau_0$ & 3.4 $\pm$ 0.7 & 1.6$\pm$ 1.0\\ \hline $\alpha$ & 0.027 & 0.014 \\ \hline $\beta$ & 0.042 & 0.023 \\ \hline \end{tabular}\label{tab1} \end{center} \end{table} The above example illustrates the case where mainly numbers are included. In the example that follows, we show equations in the table, which now contains less columns than the one above. \begin{table}[htb] \begin{center} \caption{\bf Table format without intermediate line.} \begin{tabular}{|l|l|} \hline $\;\;\;\;\;\;\;\;\;\;\;\;$ Source $\rho(r,t)$ & $\,\,\;\;\;\;\;\;\;\;\;\;\;\;C(\vec{k}% _1,\vec{k}_2)-1$ \\ %$\;\;\;\;\;\;\;\;\;\;\; \rho(r,t)$ & \hline\hline {\bf A:} $e^{-r^2/2R^2}\;e^{-t^2/2\tau ^2}$ & $\,e^{-(\Delta \omega )^2\tau ^2\;}e^{-q^2R^2}/2$ \\ \hline {\bf B:} $\delta (r-R)\;e^{-t^2/2\tau ^2}$ & $\,e^{-(\Delta \omega )^2\tau ^2\,}[{\rm \sin }(qR)/(qR)]^2/2\,$ \\ \hline {\bf C:} $\Theta (R-r)\;e^{-t^2/2\tau ^2}$ & $\;\;\;\;\; \left( 9/2 \right) \,e^{-(\Delta \omega )^2\tau ^2} \{(qR)\}^{-4} $ \\ & $\{\,[{\rm \cos }(qR)-{\rm \sin }(qR)/(qR)]\}^2$ \\ \hline {\bf D:} $e^{-r/R}\;\Theta (3\tau ^2-t^2)$ & $\left[ \sin (\Delta \omega \sqrt{3}\,\tau )/\Delta \omega \sqrt{3}\,\tau \right] ^2$ \\ & $\;\left( 1+q^2R^2\right) ^{-4}/2$ \\ \hline {\bf E:} & $9\left| I\right| ^2/(8\mu ^6),$ \\ $\Theta (\dot{R}\,t-r)\,e^{-t^2/\tau ^2}\Theta (t)$& $I=-i\sqrt{\pi } [ (1+\mu z^{+})W(z^{+})-$ \\ & $(1-\mu z^{-})W(z^{-}) ] -2\mu $ \\ \hline \end{tabular} \label{tab2} \end{center} \end{table} The captions to the tables should be included at the top, as shown in both Table~\ref{tab1} and Table~\ref{tab2}. \section{PostScript figures} Please note that you may try and include your figure in the desired place, by choosing \verb|\begin{figure}[h]|, or by varying the choice in the square brackets at will. If you leave the options to be \verb|\begin{figure}[htb]|, {\LaTeX{} will choose the most appropriate location for your figure. \subsection{Example: single figure} \begin{figure}[!htb1] \begin{center} \includegraphics*[angle=0, width=7cm]{gaussbosferm.eps} \end{center} \caption{\emph{ \small Simple illustration corresponding to the ideal Gaussian source. The upper curve represents to the bosonic case, while the lower curve, the fermionic one. The parameter $R$ is the r.m.s. radius of the emitting region.}} \end{figure} For the figures, use PostScript files which are included into your \LaTeX{} file and print together with the text. Use one of the packages from \LaTeX's {\it graphics} directory: {\it graphics}, {\it graphicx} or {\it epsfig}, with the \verb|\usepackage| command, and then use the appropriate commands \linebreak (\verb|\includegraphics|) %or \verb|\epsfig|) to include your PostScript file, in the eps format. The simplest command is: \verb|\includegraphics{file}|, which inserts the PostScript file \texttt{file} at its own size. The starred version of this command: \verb|\includegraphics*|\hfilneg\ \noindent\verb|{file}|, does the same, but clips the figure to its bounding box. With the {\it graphicx} package one may specify a series of options as a key--value list, e.g.: \begin{tabular}{@{}l} \verb|\includegraphics[width=15pc]{file}|\\ \verb|\includegraphics[height=5pc]{file}|\\ \verb|\includegraphics[scale=0.6]{file}|\\ \verb|\includegraphics[angle=90,width=20pc]{file}| \end{tabular} \medskip \subsection{Example: double figure} If you would like to include more than a single picture in the same figure environment, you may proceed as in the examples below: \begin{figure}[!hbt2] %\hskip2mm \resizebox{12pc}{!}{\includegraphics{gaussbosferm.eps}}\vskip1cm \resizebox{12pc}{!}{\includegraphics{gaussbosferm.eps}} %\vskip1cm\resizebox{13pc}{!}{\includegraphics{gaussbosferm.eps}} \caption{Illustration corresponding to the usage of two plots into a single \sl{figure} environment.} \end{figure} \medskip \subsection{Example: triple figure} Alternatively, you may try to put two in the side by side and one on the bottom, as follows \begin{figure}[!htb3] %\hskip-0.6cm \resizebox{10pc}{!}{\includegraphics{gaussbosferm.eps}}%\\ \resizebox{10.5pc}{!}{\includegraphics{gaussbosferm.eps}} \resizebox{10.5pc}{!}{\includegraphics{gaussbosferm.eps}}\\ % \resizebox{10.5pc}{!}{\includegraphics{gaussbosferm.eps}} \caption{\emph{\small Illustration corresponding to the usage of three plots into a single \sl{figure} environment. }} \end{figure} % \section{EQUATIONS} Use the {\sl equation} environment to write an equation. \begin{equation} N_1({\mathbf k}_i) = \omega_{{\mathbf k}_i}\frac{d^3N} {d{\mathbf k}_i} = \omega_{{\mathbf k}_i} \langle \hat{a}^{\dagger}_{{\mathbf k}_i} \hat{a}_{{\mathbf k}_i} \rangle \;, \label{spec1}\end{equation} Use the {\sl eqnarray} environment for multi-line equations, \begin{eqnarray} && N_2({\mathbf k}_1,{\mathbf k}_2) = \omega_{{\mathbf k}_1} \omega_{{\mathbf k}_2} \langle \hat{a}^\dagger_{{\mathbf k}_1} \hat{a}^\dagger_{{\mathbf k}_2} \hat{a}_{{\mathbf k}_2} \hat{a}_{{\mathbf k}_1} \rangle \nonumber\\ &=& \omega_{{\mathbf k}_1} \omega_{{\mathbf k}_1} \{ \langle \hat{a}^{\dagger}_{{\mathbf k}_1} \hat{a}_{{\mathbf k}_1} \rangle \langle \hat{a}^{\dagger}_{{\mathbf k}_2} \hat{a}_{{\mathbf k}_2} \rangle + \langle \hat{a}^{\dagger}_{{\mathbf k}_1} \hat{a}_{{\mathbf k}_2} \rangle \langle \hat{a}^{\dagger}_{{\mathbf k}_2} \hat{a}_{{\mathbf k}_1} \rangle \nonumber\\ && \hskip.2cm + \hskip.2cm \langle \hat{a}^{\dagger}_{{\mathbf k}_1} \hat{a}^{\dagger}_{{\mathbf k}_2} \rangle \langle \hat{a}_{{\mathbf k}_1} \hat{a}_{{\mathbf k}_2} \rangle \} \;. \label{spec2}\end{eqnarray} or when you have several equations under the same numbering \begin{eqnarray} q_\parallel &=& {\bf q} . \frac{\bf K}{|\bf K|} \nonumber\\ {\bf q_T} &=& {\bf q} - {\bf q_\parallel} \nonumber\\ q_{_0} &=& E_1 - E_2 \approx \frac{1}{2m}({\bf k}^2_1 - {\bf k}^2_2) \nonumber\\ &\approx& \frac{1}{2m} ({\bf k}_1 - {\bf k}_2) . ({\bf k}_1 + {\bf k}_2) \propto q_\parallel \;.\label{qKPG}\end{eqnarray} \\ \section{BRIEF CONCLUDING REMARKS} As you can see, this template is supposed to work well for everybody. Thus, we hope that at the end, we will have a nice and uniform volume of the Proceedings of the WPCF 2006, for$\;$ everybody's enjoyment. %\acknowledgments \subsection{Acknowledgments} We would like to express our gratitude for your participation in the WPCF 2006.
