In this paper, we characterize all polynomial sets which are at the same time d-orthogonal and Δω-Appell. The resulting polynomials reduce to Charlier polynomials for (d,ω)=(1,1). Various properties of the obtained polynomials are singled out: generating function, recurrence relation of order d + 1 and a difference equation of order d + 1. We also explicitly express the d-dimensional functional for which the d-orthogonality holds.
