Physicists at the Fermi National Accelerator Laboratory are planning to announce Wednesday that they have found a suspicious bump in their data that could be evidence of a new elementary particle or even, some say, a new force of nature.
One possible explanation for this mysterious bump, scientists say, is that it is evidence of a new and unexpected version of the long-sought Higgs boson. This is a hypothetical elementary particle that, according to the reigning theory known as the Standard Model, is responsible for endowing other elementary particles with mass.
Another explanation might be that it is evidence of a new force of nature - in addition to gravity, electromagnetism, and the strong and weak nuclear forces we already know and are baffled by - that would manifest itself only at very short distances like those that rule inside the atomic nucleus.
