Fundamentals
Foundational concepts of neutrino physics — what a neutrino is, the three flavors, mass, helicity, and its place in the Standard Model.

What is a neutrino?
An electrically neutral, nearly massless, weakly interacting lepton.
- fundamentals
The three flavors
Electron, muon, and tau neutrinos — defined by their charged-lepton partners.
- fundamentals
Neutrino mass
From Pauli's massless postulate to the oscillation-era mass realization.
- fundamentals
Helicity and chirality
Why neutrinos appear only left-handed and why that mattered.
- fundamentals
Standard Model context
How neutrinos fit into the lepton sector and electroweak theory.
