WASHINGTON: Data from a major US atom smasher lab may have revealed a new elementary particle, or potentially a new force of nature that could expand our knowledge of the properties of matter, physicists say. The science world was abuzz with excitement Wednesday over the findings, which could offer clues to the persistent riddle of mass and how objects obtain it – one of the most sought-after answers in all of physics. But experts cautioned that more analysis was needed over the next several months to uncover the true nature of the observation, which comes as part of an ongoing experiment with proton and antiproton collisions.
