This quantity varies inversely with a particle's Compton wavelength.
This quantity varies inversely with a particle's Compton wavelength. Two types of this quantity were found equivalent by Loránd Eötvös [UT-vush] using a torsion balance, a result known as the equivalence principle. In general relativity, this is responsible for spacetime curvature. Progress was recently made on how gauge bosons acquire this property—possibly along with leptons and quarks—through the Higgs mechanism. For two objects, this quantity for each of them is directly proportional to the gravitational force between them, and this quantity is multiplied by acceleration in Newton's second law. Name this quantity, often contrasted with weight, that is measured in kilograms.
