Although this particle has not yet been found, the results announced today exclude a mass anywhere between 158 and 175 GeV/c ², with 95% probability.
The Higgs boson, called the God Particle, was proposed by Peter Higgs, Francois Englert and Robert Broût for over 40 years to explain the origin of particle masses. Scientists have suggested that all existing particles had no mass just after the Big Bang. As the universe cooled, an invisible force field, the “Higgs field”, graduated with their respective bosons.
The field remains in the cosmos and interact with any particle that it receives through a mass of bosons. The more we interact, the heavier they become, while those particles that do not interact remain massless. Despite explain and fit well in current theories of the universe, this proposition has a problem: nobody ever was able to observe the Higgs bosons to confirm it.
The difficulty is that scientists do not know the mass of the Higgs boson, which makes it even more difficult to identify. Currently, physicists look for it systematically searching a range of bodies within which he should be. The tracks have not yet explored can be analyzed by large particle accelerators like the LHC, the Hadron Collider at CERN and the Tevatron.
