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.

Kaluza-Klein states of the standard model gauge bosons: Constraints from high energy experiments
In theories with the standard model gauge bosons propagating in TeV 21 -size extra dimensions, their KaluzaKlein states interact with the rest of the SM particles confined to the 3-brane. We look for possible signals for this interaction in the present high-energy collider data, and estimate the sensitivity offered by the next generation of collider experiments. Based on the present data from the CERN LEP 2, Fermilab Tevatron, and DESY HERA experiments, we set a lower limit on the extra dimension compactification scale MC .6.8 TeV at the 95% confidence level~dominated by the LEP 2 results! and quote expected sensitivities in the Tevatron Run 2 and at the CERN LHC.

Black holes at future colliders and beyond
One of the most dramatic consequences of low-scale (~1 TeV) quantum gravity in models with large or warped extra dimension(s) is copious production of mini-black holes at future colliders and in ultra-high-energy cosmic ray collisions. Hawking radiation of these black holes is expected to be constrained mainly to our three-dimensional world and results in rich phenomenology. In this topical review we discuss the current status of astrophysical observations of black holes and selected aspects of mini-black-hole phenomenology, such as production at colliders and in cosmic rays, and black-hole decay properties, 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.

Interplay and Characterization of Dark Matter Searches at Colliders and in Direct Detection Experiments
In this White Paper we present and discuss a concrete proposal for the consistent interpretation of Dark Matter searches at colliders and in direct detection experiments. Based on a specific implementation of simplified models of vector and axial-vector mediator exchanges, this proposal demonstrates how the two search strategies can be compared on an equal footing.

Discovering a light Higgs boson with light
We evaluate the prospects for detecting a non-standard light Higgs boson with a significant branching ratio to two photons, in run II of the Fermilab Tevatron. We derive the reach for several channels: 2{gamma} inclusive, 2{gamma}+1 jet, and 2{gamma}+2 jets. We present the expected run II limits on the branching ratio of h{yields}{gamma}{gamma} as a function of the Higgs boson mass, for the case of ''bosonic,'' as well as ''top-color'' Higgs bosons.
