1. Central Exclusive Meson Pair Production in Perturbative Regime. (based on works by V.Khoze, M. RYskin and W.J. STirling and L. HArland-Lang ) (KRYSTHAL collaboration) V.A. Khoze ( IPPP, Durham & PNPI ) For more details see: ArXiV: 1105.1626

2. CEP is reported by LHCb (DIS-11) new CDF CEP results (Erik, low x-11) All measurements in agreement with Durham group (pre)dictions. CEP-spin-parity filter (KMR-00,KKMR-03 )

3. Prior to this Workshop Now 43 events (now proved to be small) (KMRS-04) (LKRS-10)

7. (M.Benayoun,V.Chernyak,-1990) 40 diagrams (4 basic) (Mariola’s talk )

8. (explicit calculation) is this easy to understand ?

14. New CDF data nicely confirm this ! (Erik’s talk) (K-factor,..)

17. New CDF data confirm both Durham predictions for CEP and strong suppression of the

22. PT expectations if no proton tagging Violation of -momentum transfer through the ‘digluon Pomeron’ In the low mass region: is small. Non-relativistic effects for spin 2. Non-PT contribution ( for spin 1, still ~ ). Spin-2 quarkonium suppression is easier to violate! for CEP (KMRS-04) pp  Y+X+Z
