bosonin
Bosonins are a hypothetical class of particles that are proposed to mediate a fifth fundamental force of nature. Currently, four fundamental forces are known: the strong nuclear force, the weak nuclear force, electromagnetism, and gravity. These forces are mediated by fundamental particles called bosons. For instance, photons mediate the electromagnetic force, and gluons mediate the strong nuclear force. The existence of a fifth force is suggested by various cosmological observations and theoretical frameworks, such as those attempting to explain dark matter or dark energy, or to unify existing forces.
If a fifth force exists, it would require its own mediating boson. These hypothetical particles have been
Research into the possibility of a fifth force and its associated bosonins is ongoing in theoretical physics.
