Chapter 11: Problem 21

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.

Short Answer

Expert verified
The Higgs boson, even if discovered and found to have mass, will not be considered the ultimate carrier of the weak force. Its role is to provide a mechanism by which particles acquire mass, and it does not directly mediate the weak force. The W+, W-, and Z bosons are the ultimate carriers of the weak force, as they are responsible for mediating the interactions between particles subject to this force.

Step by step solution

01

Understanding the weak force

The weak force (also known as the weak nuclear or weak interaction) is one of the four fundamental forces in nature, responsible for the radioactive decay of particles, such as beta decay. The other three fundamental forces are the electromagnetic force, the strong force, and gravity.
02

Understanding the carrier bosons

The weak force is mediated by three bosons, known as W+, W-, and Z bosons. These bosons are referred to as gauge bosons and are responsible for the interaction between particles subjected to the weak force. They can be exchanged between particles in a process known as a weak interaction.
03

Understanding the Higgs boson

The Higgs boson is a particle predicted by the Higgs mechanism, which is a theoretical framework that explains how particles acquire mass. The Higgs boson itself is associated with the Higgs field, a scalar field that permeates all space, and it interacts with particles to give them mass. This is different from the role of the carrier bosons of the weak force, which are responsible for the transmission of the force between particles.
04

Analyzing the role of Higgs boson as a carrier of weak force

Based on the information above, the Higgs boson is not a carrier of the weak force, even if it is discovered and found to have mass. Its role is to provide a mechanism by which particles acquire mass, and it does not directly mediate the weak force. The W+, W-, and Z bosons will still be considered the ultimate carriers of the weak force, as they are responsible for mediating the interactions between particles subject to this force.

Experimental results indicate an isolate particle with charge \(+2 / 3-\) an isolated quark. What quark could this be? Why would this discovery be important?

One of the common decay modes of the \(\Lambda^{0}\) is \(\Lambda^{0} \rightarrow \pi^{-}+\mathrm{p}\) Even though only hadrons are involved in this decay, it occurs through the weak nuclear force. How do we know that this decay does not occur through the strong nuclear force?

Suppose you are designing a proton decay experiment and you can detect 50 percent of the proton decays in a tank of water. (a) How many kilograms of water would you need to see one decay per month, assuming a lifetime of \(10^{31} \mathrm{y} ?\) (b) How many cubic meters of water is this? (c) If the actual lifetime is \(10^{33} \mathrm{y}\), how long would you have to wait on an average to see a single proton decay?

Distances to local galaxies are determined by measuring the brightness of stars, called Cepheid variables, that can be observed individually and that have absolute brightnesses at a standard distance that are well known. Explain how the measured brightness would vary with distance, as compared with the absolute brightness.

The core of a star collapses during a supernova, forming a neutron star. Angular momentum of the core is conserved, so the neutron star spins rapidly. If the initial core radius is \(5.0 \times 10^{5} \mathrm{km}\) and it collapses to \(10.0 \mathrm{km}\), find the neutron star's angular velocity in revolutions per second, given the core's angular velocity was originally 1 revolution per 30.0 days.
