Central Exclusive Production analysis

The following webpage will be filled with information about the analysis of central exclusive production (CEP) process
p+p -> p+X+p,
X = pi+pi-,  
K+K-,  pi+pi-pi+pi-,  pi+pi-K+K-,  K+K-K+K-
Preliminary plot of invariant mass of exclusively produced pion pairs in proton-proton collisions at \sqrt{s} = 200 GeV measured in the STAR experiment at RHIC

Preliminary mass plots in PDF and EPS formats are attached at the bottom of webpage.
