(physics) a fundamental particle, a gauge boson, that, together with the W-boson, mediates the weak nuclear force; it has a charge of 0

(physics) a fundamental particle, a gauge boson, that, together with the Z-boson, mediates the weak nuclear force; it has a charge of ± 1

(physics) Any of the fundamental particles that carry the fundamental forces of nature.

(physics) An elementary particle in the Standard Model, namely a boson with zero spin, that gives mass to other particles.

(physics) Any of a family of gauge bosons having a spin quantum number of one

(physics) A spinless boson that necessarily appears in models exhibiting spontaneous breakdown of continuous symmetries.

(physics) A hypothetical elementary particle that couples quarks to leptons, analogous to the W boson and Z boson, but corresponding to a new type of force predicted by the Georgi–Glashow model.

(astrophysics) A theoretical type of heavenly body composed of a form of boson that is self-repelling, what should be highly dense and bend spacetime in a manner approaching that of a black hole.

(physics) A boson which has zero spin.

(physics) Any of the three fundamental particles (the two W-bosons and the Z-boson) that transmit the weak nuclear force and have a mass about 100 times that of a proton.
