  1. Central Diffractive Production of Heavy Quarkonia. (KHRYSTHAL collaboration)  V.A. Khoze(IPPP, Durham) (based on works by V.KHoze, M. RYskin and W.J. STirling and L. HArland-Lang) 1

  2. With a bit of personal flavour (topical examples) Tevatron, RHIC and LHC. Forward proton distributions and correlations. CDP@LHC with FSC

  3. New D0 jj- results RHIC, ALICE data expected (star reactions!) Spin-Parity Analyzer (KKMR-2003) Detailed tests of dynamics of soft diffraction(KMR-02)

  5. Prospects for high accuracy (~1%) mass measurements • (irrespectively of the decay mode). • Quantum number filter/analyser. • ( 0++dominance ;C,P-even) • H ->bb opens up (Hbb- coupl.) • (gg)CED bb inLO ; NLO,NNLO, b- masseffects - controllable. • For some areas of the MSSM param. spaceCEDP may become adiscovery channel! • H→WW*/WW - an added value (less challenging experimentally + small bgds., better PUcond. ) • New leverage –proton momentum correlations (probes of QCD dynamics , CP- violation effects…) CED Higgs production at the LHC H How do we know what we’ve found?  LHC : ‘after discovery stage’,Higgs ID…… mass, spin, couplings to fermions and Gauge Bosons, invisible modes…  for all these purposes the CEDP will be particularly handy !

  6. “soft” scattering can easily destroy the gaps S²absorption effects -necessitated by unitarity (Beatriz) gap M Everybody’s ~ happy (KMR, GLMM, FHSW, KP, S.Ostapchenco. Petrov et al, BH, GGPS, MCs..) gap soft-hard factorizn conserved broken eikonal rescatt: between protons enhanced rescatt: involving intermediate partons Subject of hot discussions recently :S²enh

  7. Standard Candle Processes ‘Better to light a candle than to rant against darkness’ ( Confucius )

  8. FSC@LHC * (more coming soon ) * * Prpospects ! Our 3 measurements are all in good agreement (factor “few”) with the Durham group predictions.

  10. P-wave Bottomonia FNAL, E288 (spins- still unconfirmed) (Currently no complete theoretical description of onium properties.) (Still puzzles) (BABAR (2008)) The heaviest and most compact quark-antiquark bound state in nature 10

  12. Charmonium –like XYZ states

  13. still unobserved

  14. (maybe two different states X(3872), X(3875) )

  15. What we expect within the framework of the Perturbative Durham formalism (KMR-01, KKMR-03, KMRS-04, HKRS-10) Example, O++ -case *KNLO Strong sensitivity to the polarization structure of the vertex in the bare amplitude. Absorption is sizeably distorted by the polarization structure (affects the b-space distr.) KMR-01 KMR-02, KKMR-03, HKRS 09-10 (Gap size Forward proton distributions& correlations- possibility to test diffraction dynamics KMR-02

  21. Central Diffractive Production of (Crystal Bal -1986) 3 % . (about 0.25 of all hadronic decays (CLEO-2009) FSC@LHCb ?  (Barbieri et al (1979), NRQCD ) Suppressed non-resonant background

  23. KKMR-03 Very topical for STAR@RHIC forthcoming measurements with tagged forward protons (new KHRYSTHALresults soon to be released).

  24. KHRYSTHAL-2010

  25. ( Alice is installing counters )

  26. (And the same for Alice)

  27. , KK, , New STAR@RHIC results on CEP with tagged forward protons soon to come. Prospects of CDP studies at ALICE & LHCb (Rainer)

  28. Thank You  

  29. UNCERTAINTIES Known Unknowns N(N)LO- radiative effects (K-factors etc..) ‘…possible inadequancy of PT theory in s …’R.Barbieri et al-1980 ‘ ‘Right’ choice of gluon densities, in particular at so low scales as in the case ( potentiality of a factor of ~3 rise for the H-case ) . Complete model for calculation of enhanced absorption. -experimental widths, decays…     Unknown Unknowns Non- pQCD effects in the meson characteristics. Currently no complete description of heavy quarkonium characteristics. ‘Two gluon width does not tell the whole story.’   Gluons at so low scales, surprises are not excluded at all. Factor of 5 up or down (conservatively) 34
