binations of incoming particles are <i>p + p</i>, 
<i>pbar + p</i>, <i>pi+ + p</i>, <i>pi- + p</i>, 
<i>pi0/rho0 + p</i>, <i>phi + p</i>, <i>J/psi + p</i>, 
<i>rho + rho</i>, <i>rho + phi</i>, <i>rho + J/psi</i>, 
<i>phi + phi</i>, <i>phi + J/psi</i>, <i>J/psi + J/psi</i>.   
The strong emphasis on vector mesons is related to the description
of <i>gamma + p</i> and <i>gamma + gamma</i> interactions in a 
Vector Dominance Model framework (which will not be available for some 
time to come, so this is a bit o
