Bosonsunder
Bosonsunder is a fictional term used in speculative physics and science fiction to denote a hypothetical class of bosons that arise under an additional symmetry sometimes called the Under symmetry. In these scenarios, bosonsunder would mediate a previously unknown interaction, or modify the behavior of known forces, particularly in regimes not well tested by experiment. The concept is used as a thought tool to explore how extra symmetries could be realized and how new gauge bosons might behave.
In typical toy models, bosonsunder are envisioned as spin-1 or spin-0 particles with integer spin. They would
Criticism notes that there is no empirical evidence for bosonsunder, and that adding new gauge bosons introduces
