Q4:

Order the following particles according to their mass from least to greatest:

• Up quark
• Charm quark
• Top quark
• Higgs boson
• Electron
• AElectron, Higgs boson, top quark, up quark, charm quark
• BElectron, up quark, charm quark, Higgs boson, top quark
• CTop quark, up quark, charm quark, Higgs boson, electron
• DHiggs boson, up quark, charm quark, top quark, electron

Q7:

Which of the following particle groups is the Higgs boson part of?

• ABosons
• CFermions
• DLeptons
• EBaryons

Q8:

Each of the following Feynman diagrams shows how the Higgs Boson can decay, apart from one. Which diagram shows a decay of the Higgs boson that is not possible?

• A
• B
• C
• D
• E

Q9:

The Higgs boson has a mass of . The electron has a mass of . 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

Q10:

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.
