Chapter 12: Q32E (page 557)

(a) Determine the quark content of the antineutrons.
(b) Sketch the Feynman diagram for its $β$ decay.

Short Answer

Expert verified

(a) The antineutron must be made of $\bar{u} \bar{d} \bar{d}$ .

(b) The Feynman diagram is shown in the figure as:

Step by step solution

Given data

The quark content of neutron is $u d d$ .

Concept of Feynman diagram

A Feynman diagram describes the interactions in quantum field theory. Solid lines, and curved lines are used to represent different types of particle interactions.

Step 3:Determine the quark content of the antineutrons

(a)

We know that the quark content of neutron is $u d d$ .

This implies that the quark content of antineutron must be $\bar{u} \bar{d} \bar{d}$ .

The antineutron must be made of $\bar{u} \bar{d} \bar{d}$ .

Sketch Feynman vertex

(b)

The Feynman diagram is shown in figure 1.

Figure 1

This looks like the neutron decay diagram, except all the particles are changed to their antiparticle partners.
