A_4的中微子三重极大混合

Neutrino Tribimaximal Mixing from A_4 Alone

Ernest Ma

摘要:

中微子三重极大混合是由A_4在带电轻子区破缺到Z_3,在中微子区破缺到Z_2得到的。为了强化这种冲突的模式,通常会调用额外的粒子和对称性,通常伴随着不可重正化的相互作用,甚至额外的维度。本文在一个特殊的可重整化模型中说明了A_4如何在轻子数的帮助下单独实现这一点。

英文摘要:

Neutrino tribimaximal mixing is obtained from the breaking of A_4 to Z_3 in the charged-lepton sector and to Z_2 in the neutrino sector. To enforce this conflicting pattern, extra particles and symmetries are usually invoked, often accompanied by nonrenormalizable interactions and even extra dimensions. It is shown here in a specific renormalizable model how A_4 alone will accomplish this, with only the help of lepton number.
