Abstract
Continuing with our previous work on D-term triggered dynamical supersymmetry breaking, we consider a system in which our generic N=1 action is minimally extended to include the pair of Higgs doublet superfields charged under the overall U(1) as well as mu and B mu terms. The gauge group is taken to be SU(3)_C times SU(2)_L times U(1)_Y times U(1). We point out, among other things, that the Higgs mass less than the Z-boson mass at tree level can be pushed up to be around 126 GeV by D-term contributions of the overall U(1). This is readily realized by taking a U(1) gauge coupling of O(1).

We have examined Higgs mass in the theory of D-term-triggered dynamical SUSY
Since the Higgs doublets are charged under the overall U (1) in our framework, the soft scalar Higgs masses are induced by the overall
Summary
Before going into the analysis on the objective of this letter, we summarize here the basic qualitative features of the mechanism of D-term-triggered dynamical supersymmetry breaking proposed in [6,7,8]. The SUSY breaking scale, namely the order parameter hD0 i, is found to be given by their geometric mean; hD0 i ∼ Mprep Msup (see Equation (3.13) of [8] for the derivation). The solution to the gap equation itself (which was obtained from the D variation of tree and one-loop effective action) demonstrates the generation of the SUSY breaking term. All of these discussions are, consistent with perturbative SUSY non-renormalization theorem, which applies to the F -term alone. The SUSY breaking scale is much larger than the electroweak scale, but still much smaller than the cutoff
