Let U(a, A) be a representation of the Poincard group ~ with mass and helicity zero, realized in the space of C ~-functions with compact support on IR 3 , without the origin. Let U(2)(a, A) denote the tensorial product of U(a, A) by itself. We explicitly determine the cocycles of extension of U(a, A
