Chapter 33: Q22CQ (page 1211)

Suppose leptons are created in a reaction. Does this imply the weak force is acting? (for example, consider \(\beta \)decay.)

Short Answer

Expert verified

Yes, creation of leptons in a reaction signifies action of weak force.

Step by step solution

01

Definition of Concept

In case of\(\beta \) decay Leptons particles are created by the weak interactions, but in actual leptons feel weak force as well as electromagnetic type of force.

02

Explain given statement the weak force is acting

Yes, the formation of leptons in a reaction denotes the action of a weak force. The radioactive decay is caused by the weak nuclear force, which can change the quarks or leptons. They cause massive quarks and leptons to decay into lighter quarks and leptons. Normally, energy and mass are conserved during decay, but the transformed particle has a lower mass than the original particle.

Therefore, yes, the formation of leptons in a reaction denotes the action of a weak force.

Suppose a \[{{\rm{W}}^{\rm{ - }}}\]created in a bubble chamber lives for \[{\rm{5}}{\rm{.00 \times 1}}{{\rm{0}}^{{\rm{ - 25}}}}{\rm{\;s}}\]. What distance does it move in this time if it is traveling at \[{\rm{0}}{\rm{.900c}}\]? Since this distance is too short to make a track, the presence of the \[{{\rm{W}}^{\rm{ - }}}\]must be inferred from its decay products. Note that the time is longer than the given \[{{\rm{W}}^{\rm{ - }}}\]lifetime, which can be due to the statistical nature of decay or time dilation.

Gluons and the photon are massless. Does this imply that the W+. W- and Z0 are the ultimate carriers of the weak force?

Explain how conservation of baryon number is responsible for conservation of total atomic mass (total number of nucleons) in nuclear decay and reactions.

If the Higgs boson is discovered and found to have mass, will it be considered the ultimate carrier of the weak force? Explain your response.

Consider an ultrahigh-energy cosmic ray entering the Earth’s atmosphere (some have energies approaching a joule). Construct a problem in which you calculate the energy of the particle based on the number of particles in an observed cosmic ray shower. Among the things to consider are the average mass of the shower particles, the average number per square meter, and the extent (number of square meters covered) of the shower. Express the energy in \({\rm{eV}}\) and joules.
