ATLAS and the LHC
High-energy physics is about to take a major step forward. Early next year, the Large Hadron Collider will begin to smash protons together at an energy of 7 TeV, more than triple the energy of the previous highest-energy machine, the Fermilab Tevatron. A year later, collisions should reach the final energy of 14 TeV, and at much larger luminosities, opening a large new window of opportunity to see heavy new particles. The ATLAS detector, located at one of the four LHC collision points, is poised to collect the interesting collisions and reconstruct them in unprecedented detail. In this colloquium, Haas will provide a look at how these fantastic machines work and their current operational readiness. Then he'll discuss how ATLAS will look for important new physics, such as Higgs bosons and Supersymmetry, and what these or other discoveries could add to our understanding of nature.
