US ATLAS Hadronic Final State Forum: Joint Theory/Experiment Open Session

Monday 3 Dec 2012, 08:00 → 18:00 America/Chicago

308 (Gleacher Center)

Ariel Gustavo Schwartzman (SLAC National Accelerator Laboratory (US)), David Miller (University of Chicago (US)), Michael Begel (Brookhaven National Laboratory (US)), Peter Loch (University of Arizona (US))

This is the Joint Theory/Experiment Open Session of the annual US ATLAS Hadronic Final State Forum meeting. This session features summary talks on recent experimental results from ATLAS and CMS in the morning, as well as selected topical talks from both experiments on the issues and advancements in the use and tagging of objects in hadronic final states. In the afternoon we have overview talks from theory concerning expectations for new physics from LHC and modern jet findings, in addition to selected topical talks on heavy flavor, massive hadronic particles, and even the Higgs.

09:00 → 09:30 Introduction

Introduction to the format of the workshop, practical information related to lunches and social activities, etc.
