Weinberg angle  

Définition(s)

  • The weak mixing angle or Weinberg angle is a parameter in the Weinberg–Salam theory of the electroweak interaction, part of the Standard Model of particle physics, and is usually denoted as θ_w. It is the angle by which spontaneous symmetry breaking rotates the original W⁰ and B⁰ vector boson plane, producing as a result the Z⁰ boson, and the photon. Its measured value is slightly below 30°, but also varies, very slightly increasing, depending on how high the relative momentum of the particles involved in the interaction is that the angle is used for. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Weinberg_angle)
