"The Large Hadron Collider is conceived as a discovery machine that will revolutionize our understanding of the physics of elementary particles and their interactions. So far the CMS experiment at the LHC has collected roughly 20 fb-1 of data, at a center of mass energy of 8 TeV during 2012, and the hunt for exotic new phenomena has covered many…

The covariant holographic entanglement entropy formula expresses the entropy of a given region in terms of the area of a certain spacelike surface in the bulk. In holographic models of thermalization involving gravitational collapse, it has been observed that this extremal surface probes the region behind the event horizon. This leads to the…

A summary of results from CMS on the recently discovered Higgs boson is presented. Of particular importance are the Higgs couplings. Results to date are consistent with standard model expectations, but are limited in precision owing to a lack of statistics. Prospects for future improvements at an upgraded LHC, which will be capable of…

The discovery of a new boson compatible with the expectations for the Standard Model Higgs propelled LHC physics into a new era. Studying the properties and couplings of the newly discovered particle immediately became a goal of primary importance. The di-tau final state currently provides the only means of probing the coupling of the Higgs to…

Neutrino masses provide a direct window into Physics Beyond the Standard Model. It is an open question whether massive neutrinos are Majorana fermions or Dirac fermions. Majorana neutrinos, which violate lepton number conservation, offer an intriguing mechanism for generating small neutrino masses. The most practical experimental approach for…

ALICE (A Large Ion Collider Experiment) is a dedicated heavy ion experiment at Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN). The goal of the experiment is to study strongly interacting matter at extreme energy densities (QCD thermodynamics). Statistical QCD predicts that, at sufficiently high densities, there…

Experiments at the Large Hadron Collider (LHC) have discovered a new particle that appears to be the long-sought Higgs Boson. To confirm that this particle has all the properties predicted by the Standard Model of Particle Physics, its couplings to fermions must be observed directly. The most common Higgs decay is to pairs of bottom quarks, but…

The possibilities for future directions of precision Higgs physics from the current results and extrapolations at the LHC to a wide range of potential upgrades and new collider facilities are presented and compared. The strategies for producing simulation results and the benchmarks for physics and detector performances are discussed. This…

We present searches in the top-quark, dark matter and BSM Higgs sectors at the CDF and ATLAS experiments. We present a search for fourth generation quarks at the ATLAS detector using a novel W identification method. We search for a new particle resonance that might explain the CDF observed top-quark asymmetry at CDF and ATLAS. We also describe a…

Abstract: I will discuss how in a general N = 1 supergravity with N ≫ 1 scalar fields, an exponentially small fraction of the de Sitter critical points are metastable vacua. For random superpotentials and Kähler potentials, the Hessian matrix is well-approximated by a simple matrix model, from which the eigenvalue spectrum can be obtained…

One of the challenges of 21st century particle physics is a deficit of observations to constrain/shape hypotheses for what may be "the"Theory Of Everything, or at least a next stage in our development of such. I present one of the searches motivated by cosmological evidence for particulate dark matter, which aims to unearth signals in the wide…

2011 has been the year when the Large Hadron Collider (LHC) became the world's leading experimental facility in the area of the fundamental particle interactions. The amount of data available for analysis is increasing exponentially. The search for the Higgs boson is entering its final phase and it is very likely that we will know for sure if…

I will report on recent results from the Tokai-to-Kamioka (T2K) experiment, which aims to make high sensitivity and precise studies of neutrino oscillation using an intense off-axis muon neutrino beam produced by the Japan Proton Accelerator Complex (J-PARC) and directed towards the Super Kamiokande (SK) detector 295 km away. By searching for the…

After decades of preparation, the experiments at the Large Hadron Collider (LHC) are taking the first steps toward resolving many long-standing puzzles about fundamental physics at the weak scale. There were high expectations for early discovery of Supersymmetry (SUSY) at the beginning of the LHC search program. This talk summarizes the…

"Directional Detection for Dark Matter and Neutrino Physics"
Recently there has been great interest in gas-filled time projection chambers for low-background physics, motivated by searches for directional dark matter detection, neutrino-less double beta decay, and neutrino magnetic moments. The unique feature of such detectors is the…

Jets produced in collisions at the CERN LHC can be reconstructed using the charged-particle tracks measured in the ATLAS Inner Detector. Jets are produced copiously at the LHC, and can be used to study the details of the strong interaction, the hot dense medium produced in heavy ion collisions, and new fundamental particles. Track-based jet…
