Tau

Hypothetical particle in physics.

Tau (τ) refers to a hypothetical particle in physics, particularly associated with theoretical models involving neutrino oscillations and extensions of the Standard Model. It is distinct from tau (τ), a Greek letter used in mathematics.

Tau is derived from the 20th letter of the Greek alphabet.

Tau is a tiny particle, like an electron but much heavier, that scientists think might exist in our universe.
