| Charge Opinion1 #722601 The sensitivity of a particle to a fundamental interactions. They are respectively called electric charge for the electromagnetic interaction, weak isospin for the weak interaction, and colour for the strong interaction. If the charge of a particle is null the particle is insensitive to the corresponding interaction. If its is not, the higher the charge the stronger the effect. For example, electrons have an electric but no strong charge, meaning that the strong interaction does not affect them. |
