Quantum mechanics aspects and subtleties of neutrino oscillations

Understand

Neutrino oscillations appear to be a simple quantum mechanical phenomenon.

• However, a closer look at them reveals a number of subtle points and apparent paradoxes.
• Some of the basic issues of the theory of neutrino oscillations are still being debated.
• I discuss, from a historical perspective, how the role of quantum mechanical aspects of neutrino oscillations was realized in the course of the development of the theory of this phenomenon.
