Bosons and Feynman Diagrams

Which of these is the exchange boson for the strong nuclear force?

• The gluon

• The W^-

• The W⁺

• The Z⁰

Answer explanation

The exchange boson for the strong nuclear force is the gluon. It mediates the interaction between quarks and holds them together within atomic nuclei.

Why do some radioisotopes undergo Beta-minus decay?

• Their nucleus contains too many electrons and they need to eject them

• Their nucleus has too many protons and is unstable

• Their nucleus has too many neutrons and is unstable

• Electrons fall into the nucleus from the inner shell and are then ejected

Answer explanation

Some radioisotopes undergo Beta-minus decay because their nucleus has too many neutrons and is unstable.

In beta-plus decay which force exchange particle is involved?

• W⁺

• W^-

• gluon

• photon

Answer explanation

In beta-plus decay, the force exchange particle involved is the W+ boson. It carries a positive charge and is responsible for the transformation of a proton into a neutron, a positron, and a neutrino.
