The Large Hadron Collider (LHC)—the world’s largest particle accelerator—is due to restart after a two-year hiatus in a matter of days. For an update on the collider and the world of particle physics, tune in tonight, Wednesday, April 1 at 7 P.M. Eastern time for a public lecture by Jon Butterworth, a physics professor at University College London who works on the LHC’s ATLAS detector. Butterworth will cover the achievements of LHC so far—especially its discovery of the long-sought Higgs boson particle—and what may be in store when the upgraded machine turns on again.
“To say that we built a 27-kilometer tunnel under the ground, filled it with the best magnets we can build, collided these particles purely to try to understand what the universe around us is made of and how it works is something to be really proud of,” Butterworth says in a trailer video previewing his talk.
The public lecture will be broadcast live on this page. The talk, “The Most Wanted Particle,” is part of a public lecture series at the Perimeter Institute for Theoretical Physics in Ontario presented by Sun Life Financial. During the live Webcast a panel of institute physicists will answer questions and provide commentary in the chat window below the video player. The panel will also be available for 30 minutes after the talk finishes to answer further questions. Online viewers can pose questions to Butterworth by tweeting to @Perimeter and using the #piLIVE hashtag.
