Quenching jets at Cern’s LHC


Geneva, Switzerland (GenevaLunch) – The high-energy collisions at Cern’s Large Hadron Collider (LHC) are creating conditions that allow scientists to observe the resulting jets, or streams of quarks and gluons, careening away from the point of collision. The collisions recreate the conditions just instants after the Big Bang, particle physicists’ term for the creation of […]

Cern says it has produced and trapped antimatter atoms (video)

Antimatter trapped and stored - Photo Cern

Geneva, Switzerland (GenevaLunch) – One of the universe’s open questions may be a step closer to being answered thanks to over 30 atoms of antihydrogen that have been trapped and stored by scientists at the European Organization for Nuclear Research, Cern. This opens the path to new ways of making detailed measurements of antihydrogen, Cern notes […]

Cern’s LHC smashes lead ions in Big Bang simulation


Geneva, Switzerland (GenevaLunch) – The Large Hadron Collider (LHC) has successfully made the transition to collisions using lead ions, instead of lighter protons, the European Organization for Nuclear Research, Cern, announced 8 November. The collision of the much heavier lead ion particles resulted in temperatures a million times hotter than those at the centre of […]

LHC – up and running Friday night!

Geneva, Switzerland (GenevaLunch) – The LHC (Large Hadron Collider) was put back into action Friday 20 November at 22:00, slightly ahead of schedule, announced Cern. The machine started up, but was quickly shut down after a problem a year ago. “The LHC is a far better understood machine than it was a year ago,” said […]
