nparticle 
is also assigned the PDG code 5000039 and is therefore called 
<i>Graviton</i> in the event record. The graviton and unparticle 
emission as well as virtual graviton and unparticle exchange processes 
are described in [<a href="Bibliography.html" target="page">Ask10</a>].

<i>Note:</i> As discussed in [<a href="Bibliography.html" target="page">Ask09</a>], for the graviton or 
unparticle emission processes the underlying Breit-Wigner mass 
distribution should be matched to the graviton mass s
