Algebra representation

WebThe answer is simple. We pick different representations of the Lorentz algebra, and then define the fields to transform under that representation! For example. Objects transforming under the trivial representation are called scalars. Objects transforming under S μ ν are called spinors. Objects transforming under J μ ν are called vectors.
