Chapter 30: Problem 3

What is the quark content of an antiproton? [Hint: Replace each of the three quarks that compose a proton with its corresponding antiquark.]

Short Answer

Expert verified
Answer: The quark content of an antiproton is (\(\bar{u}\bar{u}\bar{d}\)).

Step by step solution

01

Determine the quark content of a proton

A proton is composed of three quarks: two up quarks and one down quark. This can be represented as (uud).
02

Replace each quark with its corresponding antiquark

To find the quark content of an antiproton, we will replace the quarks in a proton with their corresponding antiquarks. The antiquark of an up quark is an anti-up quark (represented as \(\bar{u}\)), and the antiquark of a down quark is an anti-down quark (represented as \(\bar{d}\)).
03

Find the quark content of an antiproton

Replacing the quarks in the proton with their corresponding antiquarks, we get the quark content of an antiproton to be two anti-up quarks and one anti-down quark. This can be represented as (\(\bar{u}\bar{u}\bar{d}\)). So, the quark content of an antiproton is (\(\bar{u}\bar{u}\bar{d}\)).

In an accelerator, two protons with equal kinetic energies collide head-on. The following reaction takes place: $\mathrm{p}+\mathrm{p} \rightarrow \mathrm{p}+\mathrm{p}+\mathrm{p}+\overline{\mathrm{p}} .$ What is the minimum possible kinetic energy of each of the incident proton beams?
In the Cornell Electron Storage Ring, electrons and positrons circulate in opposite directions with kinetic energies of 6.0 GeV each. When an electron collides with a positron and the two annihilate, one possible (though unlikely) outcome is the production of one or more proton-antiproton pairs. What is the maximum possible number of proton-antiproton pairs that could be formed?
Two factors that can determine the distance over which a force can act are the mass of the exchange particle that carries the force and the Heisenberg uncertainty principle \([\mathrm{Eq} .(28-3)] .\) Assume that the uncertainty in the energy of an exchange particle is given by its rest energy and that the particle travels at nearly the speed of light. What is the range of the weak force carried by the \(\mathbf{Z}\) particle that has a mass of $92 \mathrm{GeV} / \mathrm{c}^{2} ?$ Compare this with the range of the weak force given in Table 30.3
Three types of sigma baryons can be created in accelerator collisions. Their quark contents are given by uus, uds, and dds, respectively. What are the electric charges of each of these sigma particles, respectively?
A proton of mass \(0.938 \mathrm{GeV} / c^{2}\) and an antiproton, at rest relative to an observer, annihilate each other as described by \(\mathrm{p}+\overline{\mathrm{p}} \rightarrow \pi^{-}+\pi^{+} .\) What are the kinetic energies of the two pions, each of which has mass $0.14 \mathrm{GeV} / \mathrm{c}^{2} ?$
