and m$_{Δ}$ ++ R are bounded in such a way that the decays A$_{R}$ → nn and Δ ++ R → ξ + $_{R}$ξ + R are kinematically forbidden. This means that the dominant decay of Δ ++ R is into two like-sign leptons, which is a great experimental signature. There is also an allowed region in parameter space which enables the decay A$_{R}$ → Δ ++ R Δ −− R . Note that the present experimental bound on m Δ ++ is 110 GeV [10]. 

As for the remaining two scalar masses from diagonalizing Eq. (14), H 0 R 2 will be heavy with m 2 H 0 R 2 = 2 λ 1 v 2 $_{4}$, whereas H 0 R 1 will be light with mass given by
