  • Unlike other fields in the standard model, the Higgs field is scalar--it doesn't act in a specific direction. Even before the Higgs was discovered, physicist Lawrence Krauss of Arizona State University in Tempe was wondering if other scalar fields existed that could interact with the Higgs field. Krauss and James Dent of the University of Louisiana at Lafayette, devised a new scalar field that does just that. The standard model says that the fields of all fundamental forces should merge at extremely high energies, meaning there's also a unified, high-energy field out there. The new scalar field would have zero energy density, but it can use the Higgs to link up to this high-energy field, and in the process it acquires energy of its own.
