Understand

We elaborate on the idea of fake particle and study its physical consequences.

When a theory contains fakeons, the true classical limit is determined by the quantization and a subsequent process of "classicization".
One of the major predictions due to the fake particles is the violation of microcausality, which survives the classical limit.
This fact gives hope to detect the violation experimentally.
