G2.00001: Top Quark: Theory Perspective Invited Speaker: I will present a theoretical perspective on the top quark, the newest and most massive ingredient of the Standard Model of particle physics. I will explain how the top fits into the Standard Model, where its large mass gives it a special role, and may be a clue that top could act as a portal to physics beyond the Standard Model. I'll explore how current and future measurements will test the Standard Model expectations for the properties of top, and may reveal the truth about the top quark. [Preview Abstract] |

G2.00002: The State of the Top Quark Physics: recent results from the Tevatron Invited Speaker: The top quark, discovered in 1995 at Fermilab, is the heaviest elementary particle observed to date. Measurements of its properties are a direct test of the Standard Model (SM) and could provide hints of new physics beyond the SM. The CDF and D0 collaborations have a large effort devoted to the study of this intriguing particle. A large data sample collected from the ongoing Run II at the Tevatron, and advance analysis techniques, have allowed these experiments to measure the top quark properties with an impressive precision. In this talk, recent results and a review of the status and prospects of the top quark physics at the Tevatron, will be presented. [Preview Abstract] |

G2.00003: Stating the Case for Top at the LHC Invited Speaker: The top quark will be a fundamental element of the early physics program at the Large Hadron Collider. Thanks to the excellent work of the Tevatron experiments, top is now a reasonably well-understood standard model particle, and its production and decay, while often complex, are predictable. As such, the top quark will be a crucial instrument for the commissioning the ATLAS and CMS detectors and the experiments' tools for physics analysis. Once the top-quark signal has been established, the experiments will be able to use it to further probe the standard model, and to begin the search for new physics that the LHC is almost certain to deliver. Standard-model studies will be based around high-statistics measurements of top-quark properties (mass, branching fractions, decay dynamics). New-physics exploration will be in topologies that are similar to those of top decay, and in channels where top production is an important background process. I will discuss the plans that CMS and ATLAS have to pursue this physics program, and the expected performance of the experiments, with a focus on what can be done in the earliest period of LHC operations.
