轻子θ_13的新预言

New Prediction For Leptonic Theta_13

S. Nandi, Zurab Tavartkiladze

摘要:

本文讨论了由两个右手单重态中微子决定狄拉克中微子质量的中微子扇形的扩展。我们表明,这种设置与味对称性可以给大的太阳和大气中微子混合和抑制Theta_13。味对称性U(1)× S_4可导出θ_23 = π/4和一个新的θ_13的预测公式(\simeq 0.015).

英文摘要:

An extension of the neutrino sector with two right handed singlet neutrinos responsible for Dirac neutrino masses is discussed. We show that this setup with flavor symmetry can give large solar and atmospheric neutrino mixings and suppressed Theta_13. The flavor symmetry U(1) x S_4 is shown to lead to Theta_23 = π/4 and a new predictive formula for the Theta_13(\simeq 0.015).
