Noun: electroweak interaction
  1. In particle physics, the unified description of two of the four known fundamental interactions of nature: electromagnetism and the weak interaction.
    "The existence of the electroweak interactions was experimentally established in two stages, the first being the discovery of neutral currents in neutrino scattering by the Gargamelle collaboration in 1973, and the second in 1983 by the UA1 and the UA2 collaborations that involved the discovery of the W and Z gauge bosons in proton-antiproton collisions at the converted Super Proton Synchrotron."

Type of: quantum field theory
