The elusive "God particle" - or Higgs boson - being sought in the Large Hadron Collider may exist in multiple forms, according to a new study.  ...

Researchers at the Fermi National Accelerator Laboratory outside Chicago observed that collisions of protons and anti-protons produced pairs of matter particles one per cent more often than they yielded anti-matter particles.

This "asymmetry" of matter and anti-matter is beyond what could be explained by the Standard Model and could be accounted for by the existence of five Higgs bosons with similar masses but different electric charges, the researchers said.

Three would have a neutral charge and one each would have a negative and positive electric charge. This is known as the two-Higgs doublet model.
