中微子质量,μ介子g-2,暗物质,锂问题和TeV-scale的稀薄成因

Neutrino masses, muon g-2, dark matter, lithium problem, and leptogenesis at TeV-scale

Chian-Shu Chen, Chung-Hsien Chou

摘要:

中微子质量非零和暗物质存在的观测证据要求物理学超越标准模型。引入了一个含有额外标量和轻子矢量类费米子的模型。通过引入Z_2对称性,可以通过单圈效应产生TeV量级的中微子质量和反常μ子磁矩.对暗物质、锂问题和稀薄成因的解释作了尝试。这种情况可以在LHC和/或未来的实验中进行测试。

英文摘要:

Observational evidences of nonzero neutrino masses and the existence of dark matter request physics beyond standard model. A model with extra scalars and leptonic vector-like fermions is introduced. By imposing a Z_2 symmetry, the neutrino masses as well as anomalous muon magnetic moment can be generated via one-loop effects at TeV-scale. An effort of explaining dark matter, Lithium problem, and leptogenesis is presented. This scenario can be tested at LHC and/or future experiments.
