\begin{abstract}
The author will not know the received date when the compuscript
is first submitted; production will insert this. Every
article includes an abstract. The abstract is a concise
summary of the work covered at length
in the main body of the article.
It is used for secondary publications and for information retrieval
purposes. Valid PACS numbers should be entered after the abstract
is finished, using the \btt{pacs} command.

{\tt$\backslash$\string pacs\{\}} should always be input,
even if empty.}

\section{First-level heading:\\ The line break was forced via
$\backslash\backslash$}
\label{sec:level1}
Here is the first sentence in Sec.\ \ref{sec:level1}, demonstrating
section cross-referencing. Note that this sample file was run
with the eqsecnum option selected.
\subsection{Second-level heading:\\ The line break was forced via
$\backslash\backslash$}
\label{sec:level2}
Here is the first sentence in Sec.\ \ref{sec:level2}, demonstrating
section cross-referencing.
The command \btt{narrowtext}
will make the text this width. The command \btt{widetext}
will make the text the width of the full page, as on page 3.
A blank input line tells \TeX\ that a new paragraph begins.
Reference citations in text use the command \btt{cite}.
In the reference section of this paper
each reference is ``tagged'' by a string (in curly brackets).
The proper form for citing in text is
\btt{cite}$\{${\it string}$\}$,
and the result is shown here \cite{smith82,jones78}.
We will cite other people \cite{smith82,jonessmith80}
and journals here. We also cite other people again (Refs.\
\cite{smith82} and \cite{jonessmith80}).
It is worth mentioning that {\it REVTEX\/} ``collapses'' lists
of reference numbers where possible. We now cite
everyone together \cite{smith82,jones78,jonessmith80}, and once again
(Refs.\ \cite{smith82,jones78,jonessmith80}).
\section{Displayed equations}
\subsection{Another second-level heading}
\subsubsection{Third-level heading:\\ The line break was forced via
$\backslash\backslash$}
\label{sec:level3}
Here is the first sentence in Sec.\ \ref{sec:level3}, demonstrating
section cross-referencing.
In \LaTeX\ there are many different ways to display equations, and a
few preferred ways are noted below.
{\it a. Fourth-level heading: Single-line equations.}
Below we have indented, single-line equations with numbers; this is
the most common type of equation in {\it Physical Review}:
\begin{equation}
\chi_+(p)\alt{\bf [}2|{\bf p}|(|{\bf p}|+p_z){\bf ]}^{-1/2}
\left(
\begin{array}{c}
|{\bf p}|+p_z\\
px+ip_y
\end{array}\right)\;,
\end{equation}
\begin{equation}
\left\{\openone234567890abc123\alpha\beta\gamma\delta%
1234556\alpha\beta{1\sum^{a}_{b}\over A^2}\right\}\label{one},
\end{equation}
Note the open one in Eq.\ (\ref{one}).
If the equation is a little wider, the equation number automatically
moves down to the next line:
\begin{equation}
\left\{abc1234567890abc1234\alpha\beta\gamma\delta%
1234556\alpha\beta{1\sum^{a}_{b}\over A^2}\right\}.
\end{equation}
When the \btt{label} command is used [cf. input
for Eq. (\ref{one})],
the equation can be referred to in text without your knowing the
equation number that \TeX\ will assign to it.
Math will indent 18.4 pt by default; not all equations will fit
within a narrow column this way. Sometimes an equation will fit
on one line when it is set flush-left with the margin.
\btt{FL} is the command to
set the math flush left:
\FL
\begin{equation}
\left\{ab12345678abc123456abcdef\alpha\beta\gamma\delta%
1234556\alpha\beta{1\sum^{a}_{b}\over A^2}\right\},
\end{equation}
\FL
\begin{equation}
\epsilon^\ast_\mu(p)\to c(V)D_V
\sum_\tau c^f_\tau \bar u(f)P_\tau
\gamma_\mu v( \bar f)\;
[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1)\;.
\end{equation}
Use \btt{FL} before every equation
that you do not want indented. If you do not use \btt{FL}, equations
will automatically indent.
The command \verb+\FR+ is also available, and sets equations
flush right.
If you have a single-line equation that you don't want
numbered, you can use the \btt{[}, \btt{]} format:
\[g^+g^+ \rightarrow g^+g^+g^+g^+ \dots ~,~~q^+q^+\rightarrow
q^+g^+g^+ \dots ~. \]
\subsubsection{Multiline equations}
Multiline equations are obtained by using the
\btt{begin$\{$eqnarray$\}$}, \btt{end$\{$eqnarray$\}$} format.
Use the \btt{nonumber}
command at the end of each line where you do not want a number:
\begin{eqnarray}
{\cal M}=&&ig_Z^2(4E_1E_2)^{1/2}(l_i^2)^{-1}
\delta_{\sigma_1,-\sigma_2}
(g_{\sigma_2}^e)^2\chi_{-\sigma_2}(p_2)\nonumber\\
&&\times
[\epsilon_jl_i\epsilon_i]_{\sigma_1}\chi_{\sigma_1}(p_1),
\end{eqnarray}
\begin{eqnarray}
\sum \vert M^{\rm viol}_g \vert ^2&=&g^{2n-4}_S(Q^2)~N^{n-2}
(N^2-1)\nonumber \\
& &\times \left( \sum_{i
