One of two research teams searching for an elusive sub-atomic particle believed to be a basic building block of the universe announced Tuesday that new data show it is more likely to be found in the lower energy ranges of the massive atom smasher being used to track it down.
Physicists are closing in on an elusive subatomic particle that, if found, would confirm a long-held understanding about why matter has mass and how the universe's fundamental building blocks behave.
Scientists hunting for an elusive subatomic particle say they have found "intriguing hints" that it exists, narrowing the search for what is believed to be a basic building block of the universe.

Scientists hunting for an elusive subatomic particle say they've found "intriguing hints" _ but not definitive proof _ that it exists, narrowing down the search for what is believed to be a basic component of the universe. The researchers added that they hope to reach a conclusion on whether the particle exists by next year.
