In this hangout we delve into the world of antimatter. How is it different from matter? What antimatter research is going on at CERN? Why? What have we learned so far and what will this research lead to? ATLAS physicist Steven Goldfarb is joined by CERN theorist Alex Arbey, Seth Zenz from the CMS experiment, and Michael Doser, Makoto Fujiwara and Masaki Hori from the antimatter experiments at CERN.
Recorded live on 29th November 2012.
The hangouts with CERN answer questions received via #askCERN on Twitter and Google+ and via YouTube and Facebook comments.
