Sažetak
We provide a review of gauge field theories with higher spin, focusing on the classical theory of massless bosons in flat Minkowski spacetime. A brief introduction to the concept of spin is provided along with a historical review of some of the most im- portant problems and accomplishments in higher spin theory, followed by a review of familiar lower spin theories. Using a particularly elegant formalism, we examine the free higher spin theory and the theory coupled to a generic external current. For both of these theories, we review their constrained and the unconstrained formu- lation, focusing our attention on the latter. We also review the existing literature, confirming the results for the non-local unconstrained formulation and correcting some calculational errors. We briefly discuss the geometrical motivation behind the construction of the basic building blocks of the theory and we entertain the possi- bility of there being a single equation of motion for all bosonic higher spin fields. Some explicit calculations obtained using computer-assisted methods are provided in the appendix, along with the relevant computer code.
