We prove an explicit central value formula for a family of complex L-series of degree 6 for GL2​×GL3​ which arise as factors of certain Garret-Rankin triple product L-series associated with modular forms. Our result generalizes a previous formula of Ichino involving Saito-Kurokawa lifts, and as an application we prove Deligne's conjecture stating the algebraicity of the central values of the considered L-series up to the relevant periods.
