Round 3: Tossup 1

Description acceptable. The mechanism that causes the W and Z bosons to have this property is initiated by spontaneous symmetry (10[1])breaking in a “Mexican hat” potential. Neutrinos were shown to have this property (10[1]-5[1])by Super-Kamiokande’s (“KAH-mee-oh-KAHN-day’s”) discovery of neutrino oscillation. Louis de Broglie (-5[1])(“duh BROY”) theorized that particles with this property (-5[1])have a nonzero wavelength. The Higgs field causes some particles to have this property. (10[4])Particles with this property must have a nonzero rest energy and cannot travel at the speed of light. (10[2])Objects with this property cause four-dimensional spacetime to curve according (10[1])to general relativity. For 10 points, describe this property of objects measuring more than zero kilograms. ■END■ (10[2]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”]
