Gauge Theories of Kac-Moody Extensions of W Algebras as Effective Field Theories of Colored W Strings

Authors: Carlos Castro

A novel invariant gauge field theory realization of Kac-Moody extensions of w(w1+∞) algebras and based on a Lie group G is constructed. The most relevant physical feature of this theory is that it describes an effective field theory of "colored" internal w(w1+∞) strings when G = SU(3). We conclude with a discussion of how these theories might provide infinite higher conformal-spins extensions of Grand Unified Models and the Standard Model in four dimensions.
