Since its discovery in 1995, the top quark has been the focus of intense study and interest owing to its very large mass and thus the potential connection to the origin of electroweak symmetry breaking.
Although a few tens of thousands of top quark events have been available for study, this has not been sufficient to precisely measure many properties of the top quark. Once the Large Hadron Collider (LHC) is in operation at full luminosity, the two general purpose experiments, ATLAS and CMS, will each collect top quark events at a rate of 8 million/year thus allowing for precision measurements of the top-quark parameters.
Any deviation from the expected properties of the top quark will indicate new physics beyond the standard model. In this talk I will discuss the current state of the LHC, the ATLAS experiment, and the top-quark studies being pursued by members of the ISU HEP group.
