We describe a bounded search for local and global anomaly-free six-dimensional (1,0) models with tensor number T=1 and gauge group containing a diagonal abelian factor U(1)R+. The abelian factor is the diagonal combination of the usual gauged U(1)R and a U(1)⊂ Sp(nH) acting on hypermultiplets. We have searched for locally and globally anomaly-free G1× U(1)R+ and G1× G2× U(1)R+ models, subject to restrictions on the ranks of the simple factors and on the maximal charges carried by matter. We find that, unlike the case of U(1)R gauged models which are relatively rare, the diagonally gauged ones offer a rich landscape. We also study the 6D vacua of these models and find that they admit supersymmetric 6D Minkowski vacua, for which the diagonal nature of the R-symmetry gauging is necessary.
