Saturation 2005 (mini-review)
This talk was given at DIS'05 (Madison, April 27-May 2, 2005). It is a brief
review of ups and downs of high density QCD during the past year.Comment: 4 pages and 1 figur
Cost of Survival for Large Rapidity Gaps
In this talk, given at "RunII QCD and weak boson WS", we report on
calculations of the survival probability of the large rapidity gap (LRG)
processes and its energy behaviour.Comment: 4 pages, 3 figure
A violation of the factorization theorem for "hard" inclusive production
This talk is a digest of Ref.[1](E.Gotsman,E. Levin and U. Maor: TAUP
2416/97, hep-ph/9705205,Phys. Lett. (in press)) where a new mechanism for hard
inclusive production, which leads to a violation of the factorization theorem
(FT), is suggested. Numericalestimates for the effect are given for high energy
hadron (nucleus) scattering.Comment: Talk at DIS97,latex file, two eps files for picture
Higgs and Heavy Quarks Diffractive Production
In this talk, given at "RunII QCD and weak boson WS", we give the highest of
reasonable estimates for the value of cross section of the double Pomeron Higgs
meson production and suggest a new mechanism for heavy quark diffractive
production which will dominate at the Tevatron energies.Comment: 4 pages, 2 figure
High energy scattering in QCD: dipole approach with Pomeron loops
This is the talk given at ``Gribov-75 Memorial Workshop on Quarks, Hadrons,
and Strong Interactions", May 22-24, 2005, Budapest. Hungary. In this talk we
discuss the BFKL Pomeron Calculus and its interrelation with thecolour dipole
approach. The two key problems we consider are the probabilistic interpretation
of the BFKL Pomeron Calculus and the possiblescenario for the asymptotic
behaviour of the scattering amplitude at high energyin QCD.Comment: 16pages, 2 figures in eps file
Nuclear modification factor for gluon jets
It is shown that the nuclear modification factor can be smaller that unity
for jet production at small and at large transverse momentum without any
violation of the factorization theorem and the initial state effects is able to
explain the nuclear modification factor of the order of the one measured by
ATLAS. In other word, initial state effects are able to describe the jet
quenching for the gluon jet production.Comment: 6 pp. and 8 figures in .eps file
In combat with nonperturbative QCD
This talk is the second part of the summary of the theory section at DIS'97.
We demonstrated that theory of the "hard" processes, based on QCD, has achieved
a better understanding of available experimental data during the past year.
This was due to the remarkable success achieved in calculating of high order
corrections in perturbative QCD (see the summary talk of S. Forte) as well as
progress in nonpertutbative QCD approaches.Comment: latex file, 15 page
