In particle physics, a radiative process refers to one elementary particle emitting another and continuing to exist.{{Citation |last=Rouan |first=Daniel |title=Radiative Processes |date=2011 |work=Encyclopedia of Astrobiology |pages=1407–1410 |editor-last=Gargaud |editor-first=Muriel |url=https://link.springer.com/referenceworkentry/10.1007/978-3-642-11274-4_1335 |access-date=2024-11-05 |place=Berlin, Heidelberg |publisher=Springer |language=en |doi=10.1007/978-3-642-11274-4 |isbn=978-3-642-11274-4 |editor2-last=Amils |editor2-first=Ricardo |editor3-last=Quintanilla |editor3-first=José Cernicharo |editor4-last=Cleaves |editor4-first=Henderson James (Jim)|url-access=subscription }} This typically happens when a fermion emits a boson such as a gluon or photon.
