  4. Some open questions: 0) Definition of diffraction: rapidity gap vs. P exchange; 1) The ratio between SD, DD and CD? 2) Integrated cross section require the knowledge of the M- dependence for all M! Low- and high M: 3) Duality in M (FMSR); 4) Structures in t: a dip in t~1 GeV^2,… 5) The background (in s and in M); 6) Exclusive-inclusive relation; 7) From elastic to inelastic diffraction (dis)continuity.

  5. Simple (but approximate) factorization relations

  19. At At the LHC, in the nearly forward direction, Pomeron exchange dominates; the rest, e.g. f-exchange, being negligible

  26. SD and DD cross sections

  27. “Reggeized (dual) Breit - Wigner” formula:

  28. SDD cross sections vs. energy. *Normalization to ~ 14 mb at 7 TeV.

  29. Approximation of background to reference points (t=-0.05)

  30. Approximation of background to reference points (t=-0.5)

  31. B-slopes for SD B-slope for SD cross section vs. t for different M2 values

  32. Double differential SD cross sections (left) Double differential SD cross sections as a functions of M2 for different t values, (right) Double differential SD cross sections as a function of t for different M2 values.

  33. Single differential integrated SD cross sections

  34. DDD cross sections vs. energy.

  35. Integrated DD cross sections (left) Single differential SD cross sections as a functions of t integrated in different M1:M2 regions. (right) Double differential SD cross sections as a function M2 integrated in region [0.0: 1.0] of t. value.

  36. Triple differential DD cross sections t = - 0.2 t = - 0.1 t = - 0.3

  37. The parameters and results

  38. Open problems: 1. Interpolation in energy: from the Fermilab and ISR to the LHC; (Inclusion of non-leading contributions); 3. Deviation from a simple Pomeron pole model and breakdown of Regge-factorization; 4. Experimental studies of the exclusive channels (p+ π,…) produced from the decay of resonances (N*, Roper?,,,) in the nearly forward direction. 5. Turn down of the cross section towards t=o?!

  39. Prospects (future plans): central diffractive meson production (double Pomeron exchange)
