Our quest to understand our Universe brings us back to one important question: why do we live in a matter-dominated Universe? We tackled fundamental questions about the nature of antimatter in this Hangout With CERN along with physicists from CERN's Antiproton Decelerator experiments, who are experts at making, storing and studying antimatter.
We revisited the Higgs boson in this Hangout With CERN, and were joined by some young students from Poland, who were on a visit to CERN.
In this Hangout With CERN, we gave you an update on the search for the Higgs boson, with news from the Hadron Collider Physics Symposium in Kyoto, Japan. We also discussed a very interesting measurement from LHCb on the very accurately predicted decay of Bs mesons into muon-antimuon pairs.
Our first ever Hangout With CERN had ATLAS physicist Steven Goldfarb, CERN theorist Alvaro De Rujula and Mick Storr from the CERN education group introduce CERN and answer some of your questions we received via #askCERN on Twitter and Google+.
