D-宇称自发破缺的TeV标度左右对称性

TeV scale Left Right Symmetry with spontaneous D-parity breaking

Debasish Borah, Sudhanwa Patra, Utpal Sarkar

摘要:

在非超对称和超对称的左右对称模型(LRSM)中研究了D宇称自发破缺的不同情形。我们从标量势的最小化和耦合常数统一的角度探讨了TeV尺度$SU(2)_R$打破尺度$M_R$的可能性,从而TeV尺度右手中微子。我们表明,虽然最小化的标量势允许的可能性,一个TeV规模的$M_R$和微小的中微子质量在LRSM自发D-宇称破缺,规范耦合统一在高规模$\sim 10^{16}$ GeV不赞成TeV规模的对称性破缺,除了在超对称的左-右(SUSYLR)模型与希格斯偶线和bidduplet。本文还讨论了中微子质量的唯象。

英文摘要:

The different scenarios of spontaneous breaking of D-parity have been studied in both non-supersymmetric and supersymmetric version of the left-right symmetric models(LRSM). We explore the possibility of a TeV scale $SU(2)_R$ breaking scale $M_R$ and hence TeV scale right handed neutrinos from both minimization of the scalar potential as well as the coupling constant unification point of view. We show that although minimization of the scalar potential allows the possibility of a TeV scale $M_R$ and tiny neutrino masses in LRSM with spontaneous D-parity breaking, the gauge coupling unification at a high scale $\sim 10^{16}$ GeV does not favour a TeV scale symmetry breaking except in the supersymmetric left-right (SUSYLR) model with Higgs doublet and bidoublet. The phenomenology of neutrino mass is also discussed.
