LHC上大额外维单重态中微子的特征

Signatures of Singlet Neutrinos in Large Extra Dimensions at the LHC

Douglas M. Gingrich

摘要:

解释为什么中微子比其他轻子轻是一个挑战。如果右手费米子在大的额外维度中传播,那么小的中微子质量就可以得到解释。费米子在大体积中的传播会对希格斯玻色子的衰变产生影响。如果希格斯玻色子在大型强子对撞机(LHC)上被发现,详细的分析可能会揭示大的额外维度的存在。本文综述了大的额外维模型的现状的背景下,希格斯玻色子玻色子的质量和基本普朗克尺度在额外维的限制。

英文摘要:

It is a challenge to explain why neutrinos are so light compared to other leptons. Small neutrino masses can be explained if right-handed fermions propagate in large extra dimensions. Fermions propagating in the bulk would have implications on Higgs boson decays. If the Higgs boson is discovered at the Large Hadron Collider (LHC), a detailed analysis may reveal the presence of large extra dimensions. This paper reviews the status of large extra-dimensional models in the context of the current limits on Higgs boson masses and the fundamental Planck scale in extra dimensions.
