Vector boson Vector boson In particle physics, a vector boson is a boson with the spin equal to 1. The vector bosons regarded as elementary particles in the Standard Model are the gauge bosons, the force carriers of fundamental interactions: the photon of electromagnetism, the W and Z bosons of the weak interaction, and the gluons of the strong interaction. Some composite particles are vector bosons, for instance any vector meson (quark and antiquark). During the 1970s and 1980s, intermediate vector bosons—vector bosons of "intermediate" mass (a mass between the two of the vector mesons)—drew much attention in particle physics. The Z
Preon of these have gained wide acceptance in the physics world. However, in a recent work de Souza has shown that his model describes well all weak decays of hadrons according to selection rules dictated by a quantum number derived from his compositeness model. In his model leptons are elementary particles and each quark is composed of two "primons", and thus, all quarks are described by four "primons". Therefore, there is no need for the Standard Model Higgs boson and each quark mass is derived from the interaction between each pair of "primons" by means of three Higgs-like bosons. In his
