Understanding the Standard Model and Majorana Fermions

What year was the Standard Model of particle physics first proposed?

• 1991

• 1983

• 1975

• 1967

What is unique about Majorana fermions compared to other particles?

• They have no mass

• They exist only in theory

• They are their own antiparticles

• They do not interact with other particles

Which particle is considered a candidate for being a Majorana particle?

• Electron

• Proton

• Photon

• Neutrino

What is the significance of double beta decay in the study of Majorana particles?

• It could demonstrate that neutrinos are Majorana particles

• It explains the formation of the universe

• It shows the decay of protons

• It proves the existence of dark matter

What is the main challenge in detecting neutrinoless double beta decay?

• Interference from cosmic rays

• Lack of technology

• High cost of experiments

• Rarity of the event

Which elements are used in experiments to detect Majorana particles?

• Iron and Nickel

• Germanium and Xenon

• Carbon and Oxygen

• Hydrogen and Helium

What is the purpose of using lead from a Roman shipwreck in experiments?

• To increase the decay rate

• To provide historical context

• To shield from background radiation

• To cool the isotopes

What is the temperature of the CUORE experiment in Italy?

• 0.1 Kelvin

• 1 Kelvin

• 0.01 Kelvin

• 10 Kelvin

Who was Ettore Majorana?

• A scientist who proposed the Standard Model

• A physicist who disappeared mysteriously

• An astronomer who studied galaxies

• A physicist who discovered neutrinos

What could the detection of Majorana particles mean for the Standard Model?

• It would challenge and expand the model

• It would disprove the model entirely

• It would confirm the model's predictions

• It would have no impact
