Atom: asking the matter

Hadrons, neutrons, quarks, gluons, or the famous Higgs particle are concepts of the atomic physics related to a big question: what is matter? “Quèquicom” visits CERN, a laboratory built 100 meters underground in Geneva, Switzerland, where the properties of some subatomic particles like hadrons are investigated from colisions in an accelerator called LHC (Large Hadron Collider). Speakers Enrique Fernández, President of the Scientific Policy Center, Jose Angel Hernandez of the University of Santiago, Antonio Perez Calero and Ricardo Vazquez, UB, and Christopher Padilla, IFAE-UAB. Atoms only account for 4% of the matter in the universe, the rest is dark energy and dark matter.The reporter Pere Renom talks to the director of underground lab Canfranc (Huesca), theoretical physicist Jose Angel Villar, to find out how they intend to detect dark matter.
