What is the phenomenon in which neutrinos change from one flavor to another as they propagate?

  1. Neutrino Mixing

  2. Neutrino Oscillations

  3. Neutrino Decay

  4. Neutrino Scattering


Correct Option: B
Explanation:

Neutrino oscillations refer to the transformation of neutrinos from one flavor (electron, muon, or tau) to another as they travel through space.

What is the primary mechanism responsible for neutrino oscillations?

  1. Weak Interactions

  2. Strong Interactions

  3. Electromagnetic Interactions

  4. Gravitational Interactions


Correct Option: A
Explanation:

Neutrino oscillations are primarily driven by weak interactions, which involve the exchange of W and Z bosons.

Which neutrino flavors are involved in oscillations?

  1. Electron and Muon

  2. Muon and Tau

  3. Electron and Tau

  4. All of the Above


Correct Option: D
Explanation:

Neutrino oscillations can occur between any two of the three neutrino flavors: electron, muon, and tau.

What is the relationship between neutrino mass and oscillations?
