I don't believe our particle accelerators have the energy required to create artificial black holes. They might - but particle accelerators produce such enormous quantities of data that any relevant information may have simply been discarded, as it was unable to be stored. However, a micro-black hole forming in a particle accelerator is...not a subtle thing, and would likely appear as some form of annihilation [i.e. mass-energy conversion] due to evaporation via hawking radiation.

Supernovae end in special types of stars - compact stars, or stellar remnants. White dwarves, neutron stars, black holes. Not 'true' stars, but the corpses of them.
