Particle Physics Independent Assignment

• For this assignment go to http://particleadventure.org/ and press start.here
• Toggle through the pages by clicking the arrows in the top right corner. You can also find a particular page by putting your cursor over the Chapter titles on the left hand side.
  • Read 'What is Fundamental', 'What is the World Made Of', What Holds It Together, and 'Particle Decays and Annihilations'. (about 60 pages)
  • Remember this unit is intended to be an introduction to particle physics. Don't get all hung up on any one concept, some of the information you don't need to know.
• After you have reviewed the web site sections indicated above review the web page"Particle Physics Classification, What You Need to Know"

• Next using what you learned from the particle adventure web site, what you need to know page, the text (if needed) and the handouts, answer the following questions
  1. Has an up quark ever been detected in isolation?
  2. In an electron positron annihilation what is the wavelength of the emitted gamma photon? (you must find the mass of the electron from the text)
  3. I'm confused?, Is a proton a barion, hadron or a quark?
  4. Identify one difference between a muon and an electron.
  5. From the handouts find the electric charge of the up and down quarks. Resolve the charge of a neutron and a proton based on the charge of the combination of quarks which make up these two baryons.
  6. The colour charge is associated with what force?
  7. Write the symbol for the antiparticle beside each of the symbols for the particles shown in the handout 'Elementary Components of Matter'. You may wish to use the chart on p 985 of the textbook to ge the information.
