大统一理论中的中微子暗能量

Neutrino Dark Energy in Grand Unified Theories

Jitesh R. Bhatt, Pei-Hong Gu, Utpal Sarkar, Santosh K. Singh

摘要:

我们研究了一个左右对称的模型,它可以容纳中微子暗能量(\nd)的建议。III型跷跷板机制被实现以给中微子质量。在对模型进行解释之后,我们通过最小化标量势和得到不同标量场所需真空期望值的条件来研究模型的相容性。然后将该模型嵌入到SO(10)大统一理论中,并由规范耦合统一的条件确定允许的对称性破缺尺度。虽然$SU(2)_{R}$破缺需要很高,但它的阿贝尔子群$U(1)_{R}$在TeV范围内破缺,这可以给出所需的中微子质量,并预测可以在LHC检测到的新规范玻色子。在这个模型中,我们详细地研究了中微子的质量,结果表明中微子的质量至少需要3个单重态费米子。

英文摘要:

We studied a left-right symmetric model that can accommodate the neutrino dark energy (\nd) proposal. Type III seesaw mechanism is implemented to give masses to the neutrinos. After explaining the model, we study the consistency of the model by minimizing the scalar potential and obtaining the conditions for the required vacuum expectation values of the different scalar fields. This model is then embedded in an SO(10) grand unified theory and the allowed symmetry breaking scales are determined by the condition of the gauge coupling unification. Although $SU(2)_{R}$ breaking is required to be high, its Abelian subgroup $U(1)_{R}$ is broken in the TeV range, which can then give the required neutrino masses and predicts new gauge bosons that could be detected at LHC. The neutrino masses are studied in details in this model, which shows that at least 3 singlet fermions are required.
