A small team of physicists that includes Jessie Shelton of the University of Illinois and David Curtin of the University of Toronto has written a paper and presented it at this year's American Physical Society meeting outlining a possible way to detect particles emitted from the Large Hadron Collider. Their idea involves constructing a new building near the LHC to house a suite of long-lived particle detectors.

The whole point of spending billions of dollars to build the LHC was to make progress toward understanding the universe and how everything in it works. Researchers there hoped to learn more by detecting the most elementary of particles by smashing protons together at high speed and looking at the pieces as they were expelled like shrapnel in a bomb blast—many of which had already been theorized. The Higgs boson was the most notorious. But since that monumental observation, researchers have begun to wonder whether the LHC will ever find some of the other proposed particles. And there is another problem—the Higgs turned out to have a smaller mass than theory suggested, which means either the theory was not quite correct, or some of its mass was lost during the collision.
