三重跷跷板机构

Triple seesaw mechanism

D. Cogollo, H. Diniz, C. A. de S. Pires

摘要:

将II型跷跷板机制拟合到I型跷跷板机制中,得到了分母中被高标度$M^3$抑制的中微子质量的计算公式。因此,轻中微子是自然获得的新物理在TeV尺度。作为有趣的结果,该机制可以通过直接产生该机制固有的TeV态在LHC上直接探测。我们证明了右手中微子的3-3-1模型自然地实现了这种跷跷板机制。

英文摘要:

On fitting the type II seesaw mechanism into the type I seesaw mechanism, we obtain a formula to the neutrino masses which get suppressed by high-scale $M^3$ in its denominator. As a result, light neutrinos are naturally obtained with new physics at TeV scale. As interesting consequence, the mechanism may be directly probed at the LHC by directly producing the TeV states intrinsic of the mechanism. We show that the 3-3-1 model with right-handed neutrinos realizes naturally such seesaw mechanism.
