超对称分裂中中微子质量的引力效应

Gravity Effects on Neutrino Masses in Split Supersymmetry

Marco Aurelio Diaz, Benjamin Koch, Boris Panes

摘要:

中微子的质量差和混合角既不能用R宇称破坏分裂超对称性来解释,也不能单独用味盲量子引力来解释。结果表明,结合这两种效果导致,在允许的参数范围内,与实验结果吻合良好。大气质量是由中微子和中性伴子的超对称混合产生的,而太阳质量是由引力通过味盲五维算符产生的。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%的误差内,这意味着约化的普朗克标度应该位于大统一理论标度附近。通过这种方式,该模型具有很强的预测性,可以在未来的实验中进行测试。

英文摘要:

The mass differences and mixing angles of neutrinos can neither be explained by R-Parity violating split supersymmetry nor by flavor blind quantum gravity alone. It is shown that combining both effects leads, within the allowed parameter range, to good agreement with the experimental results. The atmospheric mass is generated by supersymmetry through mixing between neutrinos and neutralinos, while the solar mass is generated by gravity through flavor blind dimension five operators. Maximal atmospheric mixing forces the tangent squared of the solar angle to be equal to 1/2. The scale of the quantum gravity operator is predicted within a 5% error, implying that the reduced Planck scale should lie around the GUT scale. In this way, the model is very predictive and can be tested at future experiments.
