Round 4: Tossup 1

Description acceptable. The mechanism that causes the W and Z bosons to have this property is initiated by spontaneous symmetry breaking in a “Mexican hat” potential. Neutrinos were shown to have this property by Super-Kamiokande’s (“KAH-mee-oh-KAHN-day’s”) discovery of neutrino oscillation. Louis (10[1])de Broglie (“duh BROY”) theorized that particles (-5[1])with this property have a nonzero wavelength. (-5[1])The Higgs (10[1])field causes some particles to have this property. Particles with this property must have a nonzero rest energy and cannot travel at the speed of light. Objects with this property (10[1])cause four-dimensional spacetime to curve according to general relativity. For 10 points, describe this property of objects measuring more than zero kilograms. ■END■ (10[1]0[1])

ANSWER: massive [accept descriptions of particles with positive rest mass; accept descriptions of particles with positive rest energy until “rest”; reject answers that just mention “energy”]
