Preparations for First Physics with ATLAS

This event is part of the HEE Seminar Series.

Abstract: With much anticipation, CERN’s Large Hadron Collider (LHC) is about to enter fully into its role as the world’s highest energy particle collider. This will enable us to directly address many of the biggest questions in particle physics. Hopefully some surprises are waiting on the high-energy frontier. The ATLAS detector has gone through an extensive commissioning phase with studies of calibration, cosmic ray, single beam, and low energy collision data. The ATLAS detector and collaboration are well prepared for the start of high energy LHC operations. I will discuss the commissioning process with particular attention to calorimetry and jets. I will present our plans for handling the billion events that we will record each year and how we will prepare them for physics analysis. I will discuss early measurements in the context of the Standard Model, ATLAS’ first physics publication, and early searches for new physics with jets. We expect the first high energy collisions on March 30, so hopefully we can also look together at some of the world’s first 7 TeV collisions.
