Chapter 12: Q30E (page 557)

Sketch Feynman vertex for the creation of a ←d quark and c quark.

Short Answer

Expert verified

The Feynman diagram is shown in the figure as:

Step by step solution

01

Given data

The ←d has charge +1/3, and c has charge +2/3 .

02

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.

03

Step 3:Sketch Feynman vertex 

The Feynman diagram is shown in figure 1.

Figure 1

Because the type of quark changed, it is a weak interaction.

Because←dhas charge+1/3, and c has charge +2/3, they will exchange aW+ boson.

Sketch the Feynman diagram if the proposed decay is possible.

n¯→p+e-+v¯e

In the following exercises, two protons are smashed together in an attempt to convert kinetic energy into mass and new particles. Indicate whether the proposed reaction is possible. If not, indicate which rules are violated. Consider only those for charge, angular momentum, and baryon number If the reaction is possible, calculate the minimum kinetic energy required of the colliding protons.

p+p→n+n¯+p+p¯

A lead nucleus at rest is roughly 10-14min diameter. If moving through the laboratory with a kinetic energy of 600 TeV, howthick would thenucleus be in the direction of motion?

(a) Determine the quark content of the antineutrons.

(b) Sketch the Feynman diagram for its β decay.

Why would it be argued that the range of the strong force should be infinite, and why it isn’t?
