Use for force carrier particles, quanta of characteristic quantum fields, usually gauge fields, such as the quanta of electromagnetic fields (photons), of the electroweak interactions (EW bosons), and of the strong interactions (gluons); elastic forces on on a lattice (phonons); nuclear forces (pions); gravity forces (gravitons), etc. May include conjectural particles from GUTS (like their proton-decay-inducing gauge bosons).
In particle physics, force carriers are particles that induce forces between other particles. These particles are quanta of characteristic quantum fields, usually gauge fields: the quanta of electromagnetic fields are photons, of the electroweak interactions electroweak bosons, and of the strong interactions, gluons. Pions, among others, mediate nuclear forces. Also use for gravitons mediating gravity forces.
