High Energy Physics: Finding the Building Blocks of the Universe (Public Lecture)

High Energy Physics:  Finding the Building Blocks of the Universe
Sarah Demers, Ph.D.

Yale University

Physicists accelerate particle beams to near to the speed of light, smash them into each other, and use the debris from the collisions to try to understand the basic building blocks of the universe and the forces through which they interact.  In this talk Professor Demers will describe the current highest energy machine, the Large Hadron Collider, which is located at the international laboratory, CERN.  The Large Hadron Collider accelerates protons around a 27 km ring that is buried 100 meters underground and crosses the border between France and Switzerland.  Thousands of physicists use the data from the proton collisions to test current models of physics and search for new particles and undiscovered forces.  Professor Demers will present where we stand in terms of our knowledge of the particles of the universe, including our newest find, the Higgs Boson, and discuss where we are headed.
