Definition of Z particle in English:

Z particle


  • A heavy uncharged elementary particle considered to transmit the weak interaction between other elementary particles.

    • ‘The Z particle decayed almost instantaneously, but left a distinctive trace in the collision data.’
    • ‘The W and Z particles are quite massive for elementary particles; they are roughly 100 times as massive as the proton.’
    • ‘In addition, the theory requires that the W and Z particles, like the photon, should be massless.’
    • ‘Initial operation involved low beam intensities, and these runs failed to produce W or Z particles.’
    • ‘The W and Z particles are called intermediate vector bosons and are the exchange particles for the weak interaction.’
