B. Orsted et Gk. Zhang, TENSOR-PRODUCTS OF ANALYTIC CONTINUATIONS OF HOLOMORPHIC DISCRETE-SERIES, Canadian journal of mathematics, 49(6), 1997, pp. 1224-1241
We give the irreducible decomposition of the tensor product of an anal
ytic continuation of the holomorphic discrete series of SU(2, 2) with
its conjugate.
