One of the main purposes of the Large Hard-on Collider is the search for the Higgs boson, also called the “God particle”, since it would the sub-atomic particle that explains why all other particles have mass. However, experiments conducted in the US hint that there may be up to five different such particles, not just one.
The idea of multiple Higgs bosons is supported by results gathered by the DZero experiment at the Tevatron particle accelerator, operated by Fermilab in Illinois, US.
DZero is designed to shed light on why the world around us is composed of normal matter and not its shadowy opposite: anti-matter. Researchers working on the experiment observed collisions of protons and anti-protons in the Tevatron.
The collisions produced pairs of matter particles slightly more often than they yielded anti-matter particles. The results showed a 1% difference in the production of pairs of muon (matter) particles and pairs of anti-muons (anti-matter particles) in these high-energy collisions. Physicists had already seen such differences - known as “CP violation”, but these effects were small compared to those seen by the DZero experiment. The DZero results showed much more significant “asymmetry” of matter and anti-matter - beyond what could be explained by the Standard Model.
