具有TeV W_R的SO(10)SUSY-GUT体系的电弱对称破缺和质子衰变

Electroweak Symmetry Breaking and Proton Decay in SO(10) SUSY-GUT with TeV W_R

P. S. Bhupal Dev, R. N. Mohapatra

摘要:

在最近的一篇论文中,我们提出了一类新的中微子质量超对称SO(10)模型,其中TeV标度的电弱对称性为SU(2)_L \times SU(2)_R \times U(1)_{B-L},从而使相应的规范玻色子W_R和Z'可以在大型强子对撞机上得到。我们发现,存在一个域的汤川耦合参数和对称性破缺模式,这给了一个很好的适合所有的费米子质量,包括中微子。在这个续集中,我们讨论了另一种汤川模式,它也给出了良好的费米子质量拟合,然后研究这两种模型的质子寿命的预测。与当前质子寿命实验下限的一致性要求前两代的夸克质量大于~ 1.2 TeV。我们还讨论了如何通过辐射修正使SU(2)_R \times U(1)_{B-L}和标准电弱对称性同时破缺。

英文摘要:

In a recent paper, we proposed a new class of supersymmetric SO(10) models for neutrino masses where the TeV scale electroweak symmetry is SU(2)_L\times SU(2)_R\times U(1)_{B-L} making the associated gauge bosons W_R and Z' accessible at the Large Hadron Collider. We showed that there exists a domain of Yukawa coupling parameters and symmetry breaking patterns which give an excellent fit to all fermion masses including neutrinos. In this sequel, we discuss an alternative Yukawa pattern which also gives good fermion mass fit and then study the predictions of both models for proton lifetime. Consistency with current experimental lower limits on proton life time require the squark masses of first two generations to be larger than ~ 1.2 TeV. We also discuss how one can have simultaneous breaking of both SU(2)_R\times U(1)_{B-L} and standard electroweak symmetries via radiative corrections.
