The physics theory known as quantum chromodynamics (QCD) explains how the strong force acts. The electromagnetic force formulated by quantum field theory, which is referred to as Quantum electrodynamics (QED), was built in analogy to QCD.
The emission and absorption of photons, popularly referred to as the massless "particles" of light, represent the electromagnetic interactions of charged particles in QED; these interactions are not possible amongst uncharged, electrically neutral particles.
QED and QCD
According to QED, the photon is the "force-carrier" particle that transmits or mediates the electromagnetic force. Similar to QED, QCD predicts the existence of force-carrying particles known as gluons, which transfer strong forces between matter particles that possess strong "charge," or "color."
Therefore, the strong force's influence is restricted to the behavior of quarks, which are basic subatomic particles, and composite particles made of quarks, including mesons, which are more unusually unstable particles, and the protons and neutrons that constitute the atomic nuclei. READ MORE...
