In this talk we will present results on all one-loop scattering amplitudes in N=6 Chern-Simons matter theories. Especially we will discuss connection between certain triple-cut diagrams and tree-level recursive diagrams, and a general formula capturing the multi-particle factorization of arbitrary one-loop amplitudes in the theories is obtained from this connection. Furthermore a recursion relation for the supercoefficients of one-loop amplitudes will be derived, which leads the solution for all one-loop amplitudes.
Accidental Supersymmetry and the Renormalization of Co-dimension 2 Branes

High Energy Physics
In this talk, I'll give a brief summary of how one-loop bulk eﬀects renormalize both bulk and brane eﬀective interactions for geometries sourced by codimension-two branes. I'll then discuss what these results imply for a six-dimensional supergravity model which aims to capture the features that make extra-dimensional physics attractive for understanding naturalness issues in particle physics. I'll also emphasize the role that brane back-reaction plays in yielding unexpected results, and present a one-loop contribution to the 4D vacuum energy whose size is set by the KK scale.

Two-dimensional gauge theories with (0,2) supersymmetry admit a much broader, and more interesting, class of solutions than their better studied (2,2) counterparts. In this talk, we will explore some of the possibilities that are offered by this additional freedom. The moduli spaces we find can be interpreted as the target spaces for heterotic strings moving in backgrounds with non-trivial H-flux. A remarkable relationship between (0,2) gauge anomalies and H-flux will emerge.
Light sleptons, Higgs phenomenology and the vacuum

We analyze the implications for Susy theories of a Higgs to di-photon rate enhanced, if compared to the Standard Model prediction. We show how models predicting a sizable enhancement have generically an electroweak vacuum that is not absolutely stable. In particular we discuss the only viable scenario that can predict sizable new physics effects in the di-photon rate in the framework of the MSSM: a scenario with light and heavily mixed staus. We conclude with the phenomenology of this model and with the prospects of probing it at the LHC, through the direct production of light staus.
Unitarity, black hole microstates and how Alices fuzzes but may not even know it

The information paradox and the infall problem have been long-standing puzzles in the understanding of black holes. The idea of free infall is in considerable tension with unitarity of the evaporation process and recent developements have made this tension sharp. In the first part of my talk I will address the information question and argue that unitarty requires every quantum of radiation leaving the black hole to carry information about the initial state. Unitary evaporation is thus inconsistent with an information-free horizon at every step of the evaporation process and this extends the recent firewall result. This immediately raises the question of What is the required horizon-scale structure? I will show an explicit construction of near-extremal black hole microstates which put flesh and branes on the fuzzball proposal and may realize firewalls in string theory. In the second part I will address the question of What happens to an observer falling into a fuzzball? I will argue that the answer is dependent on the energy scale of the infalling observer.
The Spectrum of Strings on Warped AdS3

Warped AdS3 has isometry SL(2,R) x U(1). It is closed related to Kerr/CFT, non local dipole theories and AdS/CMT. In this talk I will derive the spectrum of string theory on Warped AdS3. This is possible because the worldsheet theory can be mapped to the worldsheet on AdS3 by a nonlocal field redefinition.
Moduli Stabilization and Holographic RG
December 04, 2012

PIRSA:12120002
High Energy Physics
In this talk, I will relate moduli stabilization in AdS or de Sitter space to basic properties of the Wilsonian action in the holographic dual theory living on dS (of one lower dimension): the single-trace terms in the action have vanishing beta functions, and higher-trace couplings are determined purely from lower-trace ones (a property we refer to as the iterative structure of RG). In the dS case, this encodes the maximal symmetry of the bulk spacetime in a quantity which is accessible within a single observer's patch.

The LHC has made remarkable progress in exploring the SM at new energies and demonstrating remarkable agreement with theoretical predictions. In this talk I will discuss one area where the SM does not fit as well as expected, and what could be hints of new physics showing up in the electroweak sector.

PIRSA:12110094
High Energy Physics
Chern-Simons contact terms constitute new observables in three-dimensional quantum field theory. In N=2 supersymmetric theories with an R-symmetry, they lead to a superconformal anomaly. This understanding clarifies several puzzles surrounding the S3 partition function of these theories. In particular, it leads to a proof of the F-maximization principle. Chern-Simons contact terms can be computed exactly using localization and lead to new tests of proposed dualities.
