Charge
Intuitive
Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.
Concrete
In this section things should be explained by analogy and with pictures and, if necessary, some formulas.
Abstract
A particular problem is the occurrence of "charged" particles, i.e. particles which are separated from, the vacuum by some Superselection Rule, the classical example being particles with half integer spin [1]. By the very definition of superselection rules there cannot exist an observable field which generates states of such a particle out of the vacuum.Particle Structure of Gauge Theories by K. Fredenhagen
Why is it interesting?
