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.
Light sleptons, Higgs phenomenology and the vacuum

High Energy Physics
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.

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.

Light third generation superpartners are one way to avoid bounds on new physics from the early LHC. We will review the theory and phenomenology of light stops and highlight a particular UV model based a partially composite electroweak sector through Seiberg duality.
New Results in Jet Substructure
October 23, 2012

PIRSA:12100128
High Energy Physics
We present new results on the performance of jet substructure techniques and their use in distinguishing the signatures of new boosted massive particles from the QCD background. Advanced approaches to jet reconstruction using jet grooming algorithms such as filtering, trimming, and pruning are compared. Measurements of the jet invariant mass for each jet algorithm are compared both at the particle level to multiple Monte Carlo event generators and at the detector level for several configurations of the jet grooming algorithms. The performance of these strategies and improvements in search sensitivity for new boosted hadronic particles are compared. Recent results using these techniques for both boosted RPV gluinos and top quark pairs from new particles are presented. The result is a comprehensive foundation for the use of substructure algorithms in the search for new physics at the LHC

High Energy Physics
With the discovery of a new Higgs-like particle at the LHC, there is an unprecedented opportunity to use the Higgs as a probe for physics beyond the Standard Model. I will discuss a variety of recent ideas to look for new physics via the Higgs, including measurements of Higgs couplings and associated indirect observables; searches for Higgs production in association with new physics; and strategies for probing extended electroweak symmetry breaking sectors.
A Higgs but no sparticles yet: what it means for the (p)MSSM

PIRSA:12100052
High Energy Physics
The phenomenological Minimal Supersymmetric Standard Model (pMSSM) provides a broad perspective on supersymmetric phenomenology. We have generated two large sets of pMSSM models with neutralino and gravitino LSPs, with sparticle masses extending up to 4 TeV. In this talk, I will discuss the implications of searches for supersymmetry and the Higgs, with particular attention to naturalness. In particular, we find that while sparticle spectra with moderately light stops are still allowed, such stops are difficult to find experimentally because of a wide array of possible cascade decays.

The LHC detectors are allowing experimentalists to look "inside" of jets and study the properties of these. Jet substructure gives us the tools to study boosted resonances that decay into jets. In this talk, I will discuss an extension of substructure techniques to beyond the Standard Model signals where reconstructing resonances may not be optimal, but these techniques still allow us to pick out these signals from a busy QCD environment.
Smash, Bang, Boom: Fundamental Physics at the LHC

High Energy Physics
The world's most ambitious scientific experiment is buried 100 meters underground, straddling Switzerland and France. A billion times every minute, the Large Hadron Collider (LHC) slams together protons, while four giant detectors watch closely. - So how does the Large Hadron Collider work? - Why can slamming tiny particles into each other provide clues about the nature of all space and time? - What mysteries are physicists trying to solve with data from the LHC? - How does the cutting edge of particle physics relate to the world around us, from the patterns of stars in the sky to the fact that they shine at all? Natalia Toro, PI Faculty, works at the intersection of theories and hard data. She will explain how complex collision data from the LHC is being digested and examined right now, and how it may set the course for the science of the future.
