Jets as probes of QCD and new physics
Abstract: Despite its tremendous success in describing data from high energy physics experiments so far, the standard model of particle physics is still considered incomplete due to various limitations. High energy jets produced at the Fermilab Tevatron collider probe physics at the shortest distance scale currently attainable in laboratory experiments, and offer an excellent opportunity to further examine the standard model in the area of strong interactions, Quantum Chromodynamics (QCD). Jets are also powerful probes to search for new physics phenomena beyond the standard model. In this talk, I will present two studies with high energy jets, a measurement of the inclusive jet cross sections and a search for new particles decaying into two jets, at the Collider Detector at Fermilab experiment. I will also discuss future prospects of studies with jet at the Large Hadron Collider.

Automating One-loop amplitudes for the LHC
Abstract: Recently there has been much development of calculational techniques for both tree and one-loop amplitudes. These new developments of on-shell recursion relations and generalised unitarity produce in a highly efficient manner very compact results that are out of the reach of standard techniques. I will discuss the adaption of these approaches into efficient algorithms for automatic computation within the context of "BlackHat", a program for the automated computation one-loop amplitudes. |

New Strong Dynamics at the TeV Scale: from multi-jet resonances at the Tevatron to di-CHAMPs at the LHC
Abstract: Despite its great success, the standard model of particle physics fails to explain many important features of the observed world. These puzzles include the identity of dark matter and the mechanism behind "electroweak superconductivity", which deserve special attention as they seem to point to the "TeV scale", the energy scale relevant for the collider experiments at the Tevatron and the LHC. In this talk, I will introduce a class of simple extensions of the standard model with a new strong dynamics at the TeV scale. The models of this class are robustly immune to existing precision constraints. They all contain resonantly-produced spin-1 particles, and their spin-0 decay products can lead to a variety of interesting collider signatures. Generic possibilities include charged and collider-stable spin-0 particles ("CHAMPs"), which can be used at the LHC to discover the parent spin-1 particles as a di-CHAMP resonance. For the Tevatron, there is a significant discovery potential for colored resonances in multi-jet samples of the *existing* data.

Searching for the Higgs one single top at a time
Abstract: I will first review some open questions in our understanding of nature that might be accessible by high energy collider experiments. The Higgs mechanism is a proposed solution to one of these exciting questions: "What is the origin of electroweak symmetry breaking". Collisions from the Tevatron at Fermilab should be capable of producing the Higgs boson, and it's discovery - or exclusion - will bring us closer to answering this question. Electroweak single top production produces a similar signature as one important low mass search channel for the Higgs boson. Measuring the single top production cross section is an exciting SM measurement in its own right, but in addition, I will discuss how the techniques that we developed and used to increase the sensitivity of the single top search were transformed into the most sensitive low mass Higgs boson search to date.

Albert Einstein said:
Through the release of atomic energy, our generation has brought into the world the most revolutionary force since prehistoric man's discovery of fire. This basic force of the universe cannot be fitted into the outmoded concept of narrow nationalisms.
Niels Bohr said:
Those who are not shocked when they first come across quantum mechanics cannot possibly have understood it.
Max Born said:
No concealed parameters can be introduced with the help of which the indeterministic description could be transformed into a deterministic one. Hence if a future theory should be deterministic, it cannot be a modification of the present one but must be essentially different. |
