(Phys.org) —The recently discovered Higgs boson is best known for its important role in explaining particle mass. But now some physicists are wondering if the Higgs could have played an equally significant role in generating ...
(Phys.org) —Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world's largest and most powerful "atom smasher," report the first evidence of a process that can be used to test the mechanism ...

Extremely light and weakly interacting particles may play a crucial role in cosmology and in the ongoing search for dark matter. Unfortunately, however, these particles have so far proved very difficult to detect using existing ...
What do you do when a tried-and-true method for determining the sun's chemical composition appears to be at odds with an innovative, precise technique for mapping the sun's inner structure? That was the situation facing astronomers ...
