We discuss how the main features of high-energy 'soft' and 'semihard' pp collisions may be described in terms of parton cascades and multi-pomeron exchange. The interaction between pomerons produces an effective infrared cutoff, ksat, by the absorpti... Read More about Probes of multiparticle production at the LHC.

We study the Central Exclusive Production (CEP) of χcJ and ηc mesons at RHIC in proton–proton collisions. We consider the χcJ→J/ψ + γ decay channels and, recalling that the Jz=0 suppression of the J=1,2 states can be compensated by their larger branc...

We note that the definition of diffractive events is a matter of convention. We discuss two possible “definitions”: one based on unitarity and the other on Large Rapidity Gaps (LRG) or Pomeron exchange. LRG can also arise from fluctuations and we qua...
