Decay
The W and Z bosons decay to fermion–antifermion pairs but neither the W nor the Z bosons can decay into the higher-mass top quark. Neglecting phase space effects and higher order corrections, simple estimates of their branching fractions can be calculated from the coupling constants.

Famous quotes containing the word decay:
“The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.”
—Cyril Connolly (1903–1974)
“She is a prude in her own defence ... under the specious mask of propriety, she conceals the decay of her worn-out charms.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“It had been a moving, tranquil apotheosis, immersed in the transfiguring sunset glow of decline and decay and extinction. An old family, already grown too weary and too noble for life and action, had reached the end of its history, and its last utterances were sounds of music: a few violin notes, full of the sad insight which is ripeness for death.”
—Thomas Mann (1875–1955)
