| Abstract | |
In analogy to null electromagnetic fields we define null Yang-Mills (YM) fields. We show that the null non-Abelian SU & eth;N & THORN; gauge fields admit a set of 2N2 conserved "helicities." We derive null YM solutions that carry finite helicities by uplifting the Abelian Hopfion solution and their generalizations. Another method that we implement is to deform YM solutions which do not carry helicities into ones that have nontrivial helicities. A nontrivial non-Abelian solution with helicities is found as a wave of infinite energy. We also discuss non-Abelian generalizations of the Bateman parameterization for null Abelian gauge fields.
