"Exploring the unknown universe with the LHC", department colloquium, April 6, 2012, 12 noon

Daniel Whiteson, UC Irvine

Collisions at the Large Hadron Collider (LHC) let us explore a new territory nearly four times larger than anything previously examined.  This energy frontier may be populated with new particles which (1) shed light on the nature of dark matter (2) extend the current table of the fundamental particles (3) demonstrate the existence of new fundamental forces or  (4) reveal startling and completely unexpected properties.  I will describe a strategy for searching this territory, show the state of the art from the Fermilab Tevatron collider and present recent results from the ATLAS detector at the LHC.
