Chapter 33: Q28CQ (page 1211)

Identify evidence for electroweak unification.

Short Answer

Expert verified

The predictions of one massless, three massive bosons, and one massive spin=0 boson confirmed the theory.

Step by step solution

01

Definition of electroweak unification

The electroweak interaction is a fundamental force that represents the union of electromagnetic and weak nuclear interactions. Glashow, Weinberg, and Salam's work demonstrated that electromagnetic and weak nuclear forces can be understood as a single interaction.

02

Explanation

Salam, Ward, and Weinberg predicted the existence of three massive (with rough estimates, of the masses for W+, W_ and Z0 ) and one massless spin 1 bosons while researching electroweak theory (a way of relating weak with electromagnetic interactions). All of these particles have been confirmed, along with their masses.

The Higgs boson, a spin 0 massive boson, was also predicted, and the particle has recently been confirmed.

What is the wavelength of an \({\rm{50 - GeV}}\) electron, which is produced at SLAC? This provides an idea of the limit to the detail it can probe.

The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle?

Explain how the weak force can change strangeness by changing quark flavor.

A virtual particle having an approximate mass of \[{\rm{1}}{{\rm{0}}^{{\rm{14}}}}{\rm{GeV/}}{{\rm{c}}^{\rm{2}}}\]may be associated with the unification of the strong and electroweak forces. For what length of time could this virtual particle exist (in temporary violation of the conservation of mass-energy as allowed by the Heisenberg uncertainty principle)?
