Coproduct of SU_{q} (2), Coherent States and Four Point Function with Logarithmic Regge Trajectories
M. Arık, Ayşe Peker-Dobie · DergiPark (Istanbul University) · 2001
The representation of the operators belonging to a 2 \\times 2 SUq (2) matrix yield a Hilbert space H. The coproducts of these operators define a Hilbert space H(2) isomorphic to H and canonically embedded in H \\otimes H. The four-point function obtained by taking the scalar product of the ground state of H(2) with the coherent states in H \\otimes H is uniquely defined, is meromorphic and has Regge behaviour.
