US atom smasher may have found new force of nature

Physicists will announce Wednesday that data from a major US atom smasher lab may have revealed a new elementary particle, or potentially a new force of nature.... The discovery is believed to relate to mass and how objects obtain it.... the particles behave differently than the Higgs-boson, which would be decaying into heavy quarks, or particles. The new discovery "is decaying in normal quarks...." "Nobody knows what this is.... If it is real, it would be the most significant discovery in physics in half a century."
