This means that the carrier particles must indeed have mass. All cariers have a spin of 1, however. The weak force, as its name implies, is weaker than the electromagnetic or strong nuclear force , about five factors of magnitude smaller than the strong nuclear force distances in an atom's nucleus. The strong nuclear force is an interaction between color, and particles that possess color. Quarks possess one of three colors, green, red, or blue, and the strong force is an attractive force between these and the mediating particle, gluons.
Gluons have two colors, one normal color and one anti-color.
The strong force has no theoretical limit to its range, as gluons have no mass. In addition, they have no electric charge, and a spin of 1. Since color does not appear outside of any hadrons, the strong force only directly has effects inside a hadron, at distances around 10 to the negative 17th power. The previous paragraph describes the direct effects of the strong force, usually referred to as the fundamental strong interaction. The strong force also has a residual effect.
