Physicists Restart Souped-Up Hadron Collider -- CERN’s Large Hadron Collider, after a two-year shutdown, has begun a new quest to probe some of the biggest puzzles about the universe, such as dark matter and the possible presence of other dimensions.
The ALPHA experiment is a successor of an earlier antimatter experiment, ATHENA. Set up in late 2005 with similar overall research goals as its predecessor, ALPHA makes, captures and studies atoms of antihydrogen and compares these with hydrogen atoms.
A group of scientists suspect that the particle discovered by CERN scientists during experiments with the Large Hadron Collider in 2012 may not be the elementary particle Higgs Boson. It could be the techni-higgs particle.
