Study of the diffractive production of baryon states and search for cryptoexotic baryons with hidden strangeness
The reactions of baryon diffractive productionp+N→(pK+K−)+N, p+N→(pϕ)+N, p+N→[Λ(1520)K+]+N p+N→[Σ(1385)oK+]+N in the 70 GeV proton beam were studied. Very sensitive upper limits for the production cross sections of heavy narrow cryptoexotic baryon resonances with hidden strangeness were obtained.

Study of the Primakoff Reactions at High Energy
In this talk the Coulomb production reactions at high energy are discussed as well as the study of electromagnetic properties of hadrons (mesons and hyperons) in these processes. The results of previous investigations are summed together with some recent data of SELEX(Fermilab) and SPHINX(IHEP) experiments.

Black holes at future colliders and in cosmic rays
One of the most dramatic consequences of low-scale (~ 1 TeV) quantum gravity would be copious production of mini black holes at future accelerators and in ultra-high-energy cosmic ray interactions. Hawking radiation of these black holes is constrained mainly to our (3+1)-dimensional world and results in their rapid evaporation. We review selected topics in the mini-black-hole phenomenology, such as production rates at colliders and in cosmic rays, Hawking radiation as a sensitive probe of the dimensionality of extra space, as well as an exciting possibility of finding new physics in the decays of black holes.

Trilinear gauge couplings at the Fermilab Tevatron
Recent trilinear gauge boson couplings measurements by the CDF and D0 Collaborations at the Fermilab Tevatron are presented. The measurements were done by analyzing diboson production in multiple decay channels and final states. No deviations from the Standard Model description of the WWZ, WW{gamma}, ZZ{gamma} and Z{gamma}{gamma} vertices were found. Limits on anomalous gauge couplings set by these analyses are the tightest available to date.

Vanishing Dimensions and Planar Events at the LHC
We propose that the effective dimensionality of the space we live in depends on the length scale we are probing. As the length scale increases, new dimensions open up. At short scales the space is lower dimensional; at the intermediate scales the space is three-dimensional; and at large scales, the space is effectively higher dimensional. This setup allows for some fundamental problems in cosmology, gravity, and particle physics to be attacked from a new perspective. The proposed framework, among the other things, offers a new approach to the cosmological constant problem and results in striking collider phenomenology and may explain elongated jets observed in cosmic-ray data.

Production mechanism of the X(1740) meson
Abstract New data from π - p charge-exchange at 38 GeV/ c confirm the existence of the narrow X (1740) meson, observed in its ηη decay mode. The upper limit on its width is 80 MeV. It is not observed decaying into either η'η or π 0 π 0 . This meson is produced in charge-exchange by a mechanism other than OPE with a nucleon isobar (probably Δ(1232)), and not with a neutron.
