[′wēk ′kəp·liŋ]

(particle physics)

The coupling of four fermion fields in the weak interaction, having a strength many orders of magntiude weaker than that of the strong or electromagnetic interactions.

This allows quantum field theories to be investigated beyond the weak coupling regime where they may be defined as an asymptotic series in the coupling constant generated by Feynman diagrams.

Exact Results in Supersymmetric Quantum Field Theories

In these cases, weak coupling has been commonly assumed because of the low density of air and high stiffness of cabin wall, which means that the cavity's interior sound pressure would have little influence on the vibration of cavity wall, and modals of interior sound field would also be affected very lightly [5].

Contrary to, for example, a weak coupling approximation, the pure dephasing model applied in this section is exact but for the price of credibility limited to the time scales which are short with respect to the time scales of energy dissipation [14].
