We clarify the role of the fusion algebra in determining the interactions and the Chan-Paton symmetry of open-string models. Adapting the internal symmetry to the fusion algebra yields corresponding patterns of symmetry breaking, which we illustrate in a number of examples.

Abstract
We clarify the role of the fusion algebra in determining the interactions and the Chan-Paton symmetry of open-string models. Adapting the internal symmetry to the fusion algebra yields corresponding patterns of symmetry breaking, which we illustrate in a number of examples.File in questo prodotto:
