Abstract: We discuss some remarkable features of the light‐front holographic mapping of classical gravity in anti‐de Sitter space modified by a confining dilaton background. In particular, we show that a positive‐sign dilaton solution exp(+κ2z2) has better chances to describe the correct hadronic phenomenology than the negative solution exp(−κ2z2) extensively studied in the literature. We also show that the use of twist‐scaling dimensions, instead of canonical dimensions, is required to give a good description of the spectrum and form factors of hadrons. Another key element is the explicit connection of AdS modes of total angular momentum J with the internal structure of hadrons and the proper identification of the orbital angular momentum of the constituents.
