### High Energy Theory Seminar - IAS - Nima Arkani-Hamed, IAS - “Locality and Unitarity from Positivity”

High Energy Theory Seminar - IAS - Nima Arkani-Hamed, IAS - “Locality and Unitarity from Positivity”

Fri, Feb 1, 2013, 1:30 pm to 3:00 pm

### High Energy Theory Seminar - Bo Sundborg, Stockholm University - Singularities in three-dimensional gravity

Fri, Jan 25, 2013, 1:30 pm to 3:00 pm

Singular geometries are important in 3d gravity. For example, conical singularities represent point particles. There are also more surprising examples that appear naturally in 3d gravity theories.

### Condensed Matter Seminar - Tarun Grover, KITP UCSB - Highly Entangled Quantum Matter

Mon, Jan 21, 2013, 1:15 pm to 2:30 pm

Abstract: Strong correlations can lead to new phases of quantum matter with striking features, such as emergent fermions and photons in a system composed only of bosons, or even excitations that are neither bosons nor fermions ("anyons"). In this talk, I will illustrate the unique view provided by many-body quantum entanglement on such intriguing...

### High Energy Theory Seminar - Silviu Pufu, MIT - Some progress in 3d QFT

Fri, Jan 18, 2013, 1:30 pm to 3:00 pm

Abstract: I will talk about computations of entanglement entropy and partition functions on curved manifolds in both supersymmetric and non-supersymmetric Lorentz-invariant QFT in 3 space-time dimensions.

### High Energy Physcis Seminar-Seth Zenz-Searches for the Higgs Boson Decaying to Bottom Quarks in the CMS Detector

Wed, Jan 16, 2013, 2:00 pm to 3:00 pm

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.

### Higgs Snowmass Workshop

Mon, Jan 14, 2013, 10:00 am to Tue, Jan 15, 2013, 5:00 pm

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.

### High Energy Theory Seminar - IAS - David Skinner, University of Cambridge; IAS - “Twistor Strings for N=8 Supergravity”

Fri, Jan 11, 2013, 1:30 pm to 3:00 pm

I'll explain a new way of looking at 4d supergravity --- as a theory of holomorphic maps into Penrose's twistor space. Allowing twistor space to have N fermionic directions, the theory is anomaly free when N=8. Via the Penrose transform, the vertex operators correspond to an N=8 Einstein supergravity multiplet.

### High Energy Physcis Seminar-Kanishk Rao-Top-quarks, Dark Matter, and BSM Higgs at CDF and ATLAS

Mon, Jan 7, 2013, 2:00 pm to 3:00 pm

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.
