摘要
中微子的质量差和混合角既不能单独由R宇称破坏的分裂超对称解释,也不能单独由味盲的量子引力解释。研究表明,在允许的参数范围内,将两者效应结合可以很好地与实验结果吻合。大气质量由超对称通过中微子与中性微子的混合产生,而太阳质量由引力通过味盲的五维算符产生。最大大气混合迫使太阳角的正切平方等于1/2。量子引力算符的标度被预测在5%的误差范围内,这意味着约化普朗克标度应位于大统一标度附近。这样,该模型具有很强的预测性,并可在未来实验中得到检验。

备注
12 pages, 9 figures; In section 3 we extend our discussion about the definition of flavor basis in order to clarify in which basis the Gravity contributions are flavor blind. In the section 4 we add some words to explain why the Gravity contributions will not affect the charged lepton mass matrix; Finally we also fixed some minor typos regarding units or plot labels
