Used to designate particles with a spin of 1; vector boson, esp. any of a group of three heavy bosons (the W± and Z0, qq.v.) thought to exist as mediators of the weak interaction.

Polonaise des Sci.: Série des Sci. Math. 7 729 Recently a hypothesis of a charged vector boson, which would mediate in weak interactions, was much discussed. 1968 M. S. Livingston Particle Physics xii. 218 The agency of this weak force is presumed to be a vector boson. 1975 Nature 3 Apr. 387/2 In a simple SU(4) scheme there is an obvious place for one ψ particle, in the same multiplet as the well established vector mesons ρ, ω and ϕ. 1976 Sci. Amer. Jan. 46/1 They are called vector bosons because the quantum-mechanical equation that describes particles with a spin of 1 takes the form of a four-dimensional vector. 1978 Nature 12 Oct. 483/1 These fermions interact through vector particles: the photon, charged and neutral massive vector bosons, and gluons, which are responsible for the electromagnetic, weak and strong interactions, respectively. 1983 Nature 27 Jan. 285 Physicists in Geneva have discovered the intermediate vector boson. < as lemmas |
