WebAug 6, 2024 · A gluon does not decay in a standard sense. There are a number of reasons, but the simplest is to consider the decay of any massless particle. The energy-momentum vector for a massless particle is ( E, p → c) which with E = ℏ ω means. P μ = ℏ ( ω, ω n ^). Here n ^ is a unit vector along the motion of the massless particle.

What Rules The Proton: Quarks Or Gluons? - Forbes

A gluon is an elementary particle that acts as the exchange particle (or gauge boson) for the strong force between quarks. It is analogous to the exchange of photons in the electromagnetic force between two charged particles. Gluons bind quarks together, forming hadrons such as protons and neutrons. … See more The gluon is a vector boson, which means, like the photon, it has a spin of 1. While massive spin-1 particles have three polarization states, massless gauge bosons like the gluon have only two polarization states because See more Since gluons themselves carry color charge, they participate in strong interactions. These gluon–gluon interactions constrain color fields to string-like objects called "flux tubes", which exert constant force when stretched. Due to this force, See more • Quark • Hadron • Meson • Gauge boson • Quark model • Quantum chromodynamics See more Unlike the single photon of QED or the three W and Z bosons of the weak interaction, there are eight independent types of gluon in QCD.
