This paper contains a discussion of unitary irreducible representations of the group U2,2 in terms of the non-compact algebra of creation and annihilation operators and some applications to massless fields. In particular, the U2,2 algebra yields discrete values for p4 energy, one of its generators. The little group and wave equations of massless fields are also derived from the Lie algebra of U2,2.
