The authors' main claim Introducing mirror particles for all the gauge and matter multiplets of the Minimal Supersymmetric extension of the Standard Model (MSSM), the measured values of sin^2 \theta_W and \alpha_3(M_Z) indicate that the N=2 threshold scale M_{S_2} cannot be lower than \sim 10^{14}GeV.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

In this letter, the possible appearance of N=2 supersymmetry at a low energy scale is investigated in the context of unified theories. Introducing mirror particles for all the gauge and matter multiplets of the Minimal Supersymmetric extension of the Standard Model (MSSM), the measured values of sin^2 \theta_W and \alpha_3(M_Z) indicate that the N=2 threshold scale M_{S_2} cannot be lower than \sim 10^{14}GeV. If the U(1) normalization coefficient k is treated as a free parameter, M_{S_2} can be as low as 10^9 GeV. On the other hand, if mirror quarks and leptons are absent and a non-standard value for k is used, N=2 supersymmetry breaking could in principle occur at the electroweak scale.

If the U(1) normalization coefficient k is treated as a free parameter, M_{S_2} can be as low as 10^9 GeV.

  • For a (surely incomplete) list of related literature, see Ref. [ref] .] In particular, multiple gravitinos seem most compelling as an evidence of extended SUSY, since the presence of the other mirror partners might look like mere presence of extra matter multiplets observationally.

  • Possible solutions to this problem would be to add fields to the theory so that the new fields fall in complete GUT multiplets [ref] , or to allow a different normalization for U(1)$_Y$ [ref] , or to contemplate different unification patterns [ref] , etc.
