Abstract: | Cubic interactions of higher-spin gauge fields in (A)dSd are studied in the metric-like approach. Making use of the traceless and transverse constraints together with the ambient-space formalism, all consistent parity-invariant cubic vertices are obtained for d?4 in a closed form pointing out the key role of their flat-space counterparts. |
