One of the three fundamental particles that transmit the weak force. The three intermediate vector bosons are known as the W+, W− , and Z0 particles or bosons. were discovered in 1983 in very high energy proton-antiproton collisions. It is through the exchange of W and Z bosons that two particles interact weakly—that is, through weak nuclear interactions—just as it is through the exchange of photons that two charged particles interact electromagnetically. As elementary particles, the intermediate vector bosons are described by the standard model of particle physics (Fig. 1).
