gluon

This term is derived from the word glue, reflecting the particle's function as the binding agent of the atomic nucleus. It describes a gauge boson that mediates the strong interaction, effectively sticking quarks together to create hadrons. As a technical term in particle physics, it is used exclusively in scientific contexts. It is a countable noun, though it is frequently discussed in the context of quantum chromodynamics (QCD) where it is treated as a field excitation.
