九重Higgs轨道GUT模型

Orbifold GUT model with nine Higgs doublets

Biswajoy Brahmachari

摘要:

我们描述了一个基于SU(5)对称性的非超对称轨道折叠大统一理论。它是Kawamura的5-D orbifold GUT模型的修正。不同之处在于希格斯标量的选择,因为我们只允许SU(5)在GUT标度中的5重态。这个变体最初由Brahmachari和Raychoudhuri提出。用额外维机制解决了质子衰变问题和二重态三重态分裂问题。统一尺度约为$5.0 \times 10^{13}$ GeV。在低能量下,有九个希格斯二重态。一个在100 GeV的区域和其他八个在1.4 TeV附近简并。它是标准模型的非超对称推广,具有非常丰富的对撞机物理现象学。

英文摘要:

We describe a non-supersymmetric orbifold GUT based on SU(5) symmetry. It is a modification of Kawamura's 5-D orbifold GUT model. The difference lies in the choice of Higgs scalars as we have allowed only 5-plets of SU(5) in the GUT scale. This variant was originally proposed by Brahmachari and Raychoudhuri. Proton decay problem and the doublet triplet splitting problems are solved by extra dimensional mechanism. The unification scale is around $5.0 \times 10^{13}$ GeVs. In low energy there are nine Higgs doublets. One at the 100 GeV region and eight others degenerate at around 1.4 TeV. It is an attractive non-supersymmetric extension of standard model with very rich collider physics phenomenology.
