Using techniques developed in a previous paper three-point functions in fieldtheories described by holographic renormalization group flows are computed. Weconsider a system of one active scalar and one inert scalar coupled to gravity.For the GPPZ flow, their dual operators create states that are interpreted asglueballs of the N=1 SYM theory, which lies at the infrared end of therenormalization group flow. The scattering amplitudes for three-glueballprocesses are calculated providing precise predictions for glueball decays inN=1 SYM theory. Numerical results for low-lying glueballs are included.Comment: 34 pages v2: comments on local terms and references added, v3: version published in JHE
