  • A
  • B
  • C
  • D
  • E


The Higgs boson has a mass of 125/𝑐GeV. The electron has a mass of 511/𝑐keV. How many times greater is the mass of the Higgs boson than that of the electron? Give your answer to 3 significant figures.

  • A245,000
  • B63,900
  • C0.245
  • D636
  • E318


The diagram shows the decay of the Higgs boson. Which of the following correctly explains why this decay is not possible?

  • AThe Higgs boson cannot interact with quarks.
  • BThe top quark has a greater mass than the Higgs boson; therefore, the rest mass energy of the Higgs boson is not large enough to produce a top quark–antiquark pair.
  • CThe interaction does not conserve electric charge.
  • DThe interaction does not conserve baryon number.
