在Randall-Sundrum模型中检验对撞机能量下的跷跷板机制

Testing the seesaw mechanism at collider energies in the Randall-Sundrum model

Hiroto Nakajima

摘要:

具有规范场和费米子的Randall-Sundrum模型具有几个吸引人的特征,包括规范耦合统一,暗物质的候选者,以及对分层汤川耦合的解释。本文指出,在对撞机上,无论是Dirac中微子还是Majorana中微子,都可能产生右手中微子的第一Kaluza-Klein模。此外,我们还可以从KK粒子的质量谱中看出中微子的质量是Dirac型还是Majorana型。

英文摘要:

The Randall-Sundrum model with gauge fields and fermions in the bulk has several attractive features including the gauge coupling unification, a candidate for the dark matter, and an explanation for the hierarchical Yukawa couplings. In this paper, we point out that the 1st Kaluza-Klein modes of right-handed neutrinos may be produced at colliders, for both Dirac and Majorana neutrino cases. Furthermore, we can see whether the neutrino masses are Dirac type or Majorana type from the mass spectrum of KK particles.
