The Yang-Baxter sigma model description was originally developed for principal chiral models based on a modified classical Yang-Baxter equation. It has been extended to coset curved spaces and models based on the usual classical Yang-Baxter equation. On the other hand, for flat space, there is the obvious problem that the standard bilinear form degenerates if we employ the familiar coset Poincar\\'e group/Lorentz group. Instead we consider a slice of AdS$_5$ by embedding the 4D Poincar\\'e group into the 4D conformal group $SO(2,4)$.
