strong force
g. Physics. Originally: descriptive of a force postulated to exist between nucleons in an atomic nucleus; (in later use) epithet of the strongest of the four known kinds of force between particles, which acts between nucleons and other hadrons when they are closer than about 10−15 m, and which conserves strangeness, parity, and isospin. Also: involving or relating to this force. Frequently in strong force, strong interaction.A consequence of the strong force is that protons in an atomic nucleus remain bound together despite the repulsive force arising from their similar electric charge.

1933 J. Chadwick in Proc. Royal Soc. A. 142 20 If the neutron consists of a proton and an electron another kind of interaction between the proton and the neutron is possible... This interaction is analogous to that between a hydrogen atom and a proton. In effect it introduces a strong repulsive field and a strong attractive field, both of very small radius of action.
1938 Proc. Royal Soc. A. 166 503 By making the former interaction strong and the latter weak it is possible to explain the large magnitude of nuclear forces and the weakness of the β-decay.
1940 Rep. Progress Physics 7 89 The strong interaction between the constituents of a nucleus.
1954 Progress Theoret. Physics 12 107/2 v-charge is defined only for such particles that have strong nuclear interactions and its conservation is violated by the weak interactions responsible for decays.
1969 R. E. Marshak et al. Theory Weak Interactions Particle Physics i. 7 Of greatest importance is the presence of the strong interaction for the meson and baryon classes but not for the lepton class.
2004 B. Greene Fabric of Cosmos (2005) iii. ix. 256 The particles of the strong force are called gluons and those of the weak force are called W and Z particles.
