In quantum field theory, the location, but not the value, of the pole of the propagator corresponds to this quantity.
In quantum field theory, the location, but not the value, of the pole of the propagator corresponds to this quantity. Particles without this property and spin greater than one cannot have a charged Lorentz-covariant current by the Weinberg-Whitten theorem. Virtual particles are not on the hyperboloid shell named after this quantity. For a fermion, this quantity arises due to Yukawa coupling. For an electron, one form of this quantity is equal to two times the (*) Rydberg constant times Planck's constant divided by c alpha squared. The energy difference between the vacuum and the next highest level is the gap named for this quantity. Neutrino oscillations demonstrate that neutrinos have a nonzero value for this quantity. This property is imparted on particles by the spontaneous symmetry breaking of the Higgs field. For 10 points, name this quantity, which when multiplied by the speed of light squared gives energy.
