These hvaey particles are only produced, for very brief moments, in high energy collisions, and are not seen in everyday life. This is because they decay very qiuklcy into the lhtegir particles.
Such decays ivlvnoe the exchange of force-carrying particles, called the W and Z, which – unlike the photon – have mass. They carry the weak force, the final force of the Standard Model. This same force allows protons and neutrons to transform into each other, a vaitl part of the fusion interactions that drive the Sun. To osrbeve the W and Z directly, we needed the high energy cioillnsos provided by particle accelerators.

These heavy particles are only produced, for very brief moments, in high energy collisions, and are not seen in everyday life. This is because they decay very quickly into the lighter particles.
Such decays involve the exchange of force-carrying particles, called the W and Z, which – unlike the photon – have mass. They carry the weak force, the final force of the Standard Model. This same force allows protons and neutrons to transform into each other, a vital part of the fusion interactions that drive the Sun. To observe the W and Z directly, we needed the high energy collisions provided by particle accelerators.
