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

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

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 in LO ; NLO,NNLO, b- mass effects - controllable. For some areas of the MSSM param. space CEDP may become a discovery channel ! H → WW */ WW - an added value ( less challenging experimentally + small bgds., better PU cond. ) New leverage –proton momentum correlations ( probes of QCD dynamics, CP- violation effects… )  LHC : ‘after discovery stage’, Higgs ID …… H How do we know what we’ve found? mass, spin, couplings to fermions and Gauge Bosons, invisible modes …  for all these purposes the CEDP will be particularly handy ! CED Higgs production at the LHC

6 “soft” scattering can easily destroy the gaps gap eikonal rescatt: between protons enhanced rescatt: involving intermediate partons M soft-hard factoriz n conserved broken Subject of hot discussions recently : S² enh S²  absorption effects -necessitated by unitarity Everybody’s ~ happy (KMR, GLMM, FHSW, KP, S.Ostapchenco.

15 What we expect within the framework of the Perturbative Durham formalism ( KMR-01, KKMR-03, KMRS-04, HKRS-10) Example, O++ -case *K NLO 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.)
