论文摘要
我们研究了中微子的辅助量规场对沙丘振荡概率引起的动力学洛伦兹对称性破坏的影响。 DLSB引入了中微子的替代能量摩尔植物关系，因此导致了新的振荡概率。我们扩展了先前提出的四摩拉纳植物模型，该模型在II型SEESAW机构后通过考虑电子中微子向前的散射在通过培养基时会产生DLSB。此外，我们结合了三种培养基中微子状态，该状态在振荡概率内引入了CP侵入性项。 DLSB参数围绕$ 10^{ - 2} -10^{ - 3} $的订单的影响，在强耦合方面，振动概率在20年内可以在Dune在20年内通过$ν_e$和$ν_e$ and $ \fllineLlineLlineLlineMeantlineBlineBlineBlineBlineBlineLlineMignlineBlineBlineNν_e$失踪信号来衡量。我们还比较了DLSB振荡的预测光谱和等于$π/2 $的CP侵略项的振荡，以结论DLSB的存在将增加测量沙丘上CP-Violation的系统不确定性。
We study the impact of the dynamical Lorentz symmetry breaking induced by the auxiliary gauge fields of neutrino on the oscillations probability at DUNE. The DLSB introduces an alternative energy-momentum relation of the neutrinos and thus results in a new oscillation probability. We extend the previously proposed four-Majorana fermion model that gives rise to DLSB after the type II seesaw mechanism by considering the electron neutrino forward scattering when passing through a medium. Moreover, we incorporate the three-flavor neutrino states, which introduce the CP-violation term inside the oscillation probability. The impact of DLSB parameters around the order of $10^{-2}-10^{-3}$, which are at a strong coupling regime, on the oscillation probability is found to be measurable at DUNE within the 20 years through $ν_e$ and $\overlineν_e$ disappearance signals. We also compare the predicted spectra of the DLSB oscillations and the oscillation with the CP-violating term equal to $π/2$ to conclude that the presence of DLSB would increase the systematic uncertainty for the measurement of CP-violation at DUNE.
