'Twisted' Clebsch-Gordan coefficients for SUq(2)

Abstract
A new approach to the Clebsch-Gordan problem for SUq(2) is proposed. The 'twisted' Clebsch-Gordan coefficients (TCGC) are defined to be the overlaps between 'twisted' connected and unconnected bases (being the q-analogues of rotated bases in standard SU(2)). The explicit expression for TCGC is found in terms of the basic hypergeometric function 4 Phi 3 (Racah q-polynomials).
