# What, specifically, creates tauons?

It is hard for me to find a site/book/article explaining how, exactly, tau particles are created.

They can be produced in a particle accelerator directly via particle + anti-particle annihilation - as long as the total energy in the center of mass system is $> 2\cdot 1776.86MeV$. For example $e^+ + e^- \rightarrow \tau^+ + \tau^-$.
An alternate pathway is when the particle + anti-particle annihilation produces a pair of heavy quarks (b or t) and at least one member of the pair decays via the weak decay into a $\tau$, $\tau$-neutrino plus other particles.
