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 Hole Production at Future Colliders
If the scale of quantum gravity is near TeV, the CERN Large Hadron Collider will be producing one black hole (BH) about every second. The decays of the BHs into the final states with prompt, hard photons, electrons, or muons provide a clean signature with low background. The correlation between the BH mass and its temperature, deduced from the energy spectrum of the decay products, can test Hawking’s evaporation law and determine the number of large new dimensions and the scale of quantum gravity. We also consider BH production at the proposed future high-energy colliders, such as CLIC and VLHC, and describe the Monte Carlo event generator that can be used to study BH production and decay.

Drell-Yan and diphoton production at hadron colliders and low scale gravity model
In the model of Arkani-Hamed, Dimopoulos, and Dvali where gravity is allowed to propagate in the extra dimensions of very large size, virtual graviton exchange between the standard model particles can give rise to signatures that can be tested in collider experiments. We study these effects in dilepton and diphoton production at hadron colliders. Specifically, we examine the double differential cross section in the invariant mass and scattering angle, which is found to be useful in separating the gravity effects from the standard model. In this work, sensitivity obtained using the double differential cross section is higher than that in previous studies based on single differential distributions. Assuming no excess of events over the standard model predictions, we obtain the following 95% confidence level lower limits on the effective Planck scale: 0.9\char21{}1.5 TeV in the Fermilab Tevatron run I, 1.3\char21{}2.5 TeV in run IIa, 1.7\char21{}3.5 TeV in run IIb, and 6.5\char21{}12.8 TeV at the CERN LHC. The range of numbers corresponds to the number of extra dimensions $n=7\ensuremath{-}2.$

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.

Search for Exotics at the Tevatron: Present and Future
We present recent results on searches for non-SUSY new physics at the CDF and D0 Collaborations in the 1992-1996 Fermilab Tevatron run. While no compelling evidence for existence of new physics was found, the Tevatron data have excluded a significant region of the theoretically allowed phase space for a variety of non-SUSY extensions of the Standard Model. Tight limits on the existence of the following new phenomena are set: leptoquarks of all three generations, quark-lepton compositeness, 4-th generation quarks, fermiophobic Higgs, technicolor, etc. Prospects of the Tevatron experiments in Run II are discussed.

LHC: Past, Present, and Future
In this overview talk, I give highlights of the first three years of the LHC operations at high energy, spanning heavy-ion physics, standard model measurements, and searches for new particles, which culminated in the discovery of the Higgs boson by the ATLAS and CMS experiments in 2012. I'll discuss what we found about the properties of the new particle in 10 months since the discovery and then talk about the future LHC program and preparations to the 2015 run at the center-of-mass energy of ~13 TeV. These proceedings are meant to be a snapshot of the LHC results as of May 2013 - the time of the conference. Many of the results shown in these proceedings have been since updated (sometimes significantly) just 4 months thereafter, when these proceedings were due. Nevertheless, keeping this writeup in sync with the results shown in the actual talk has some historical value, as, for one, it tells the reader how short is the turnaround time to update the results at the LHC. To help an appreciation of this fact, I briefly summarize the main changes between May and September 2013 in the Appendix.
