摘要:

四次方发散的真空能量在探测暗能量本质时构成了紫外(UV)挑战(宇宙常数问题)。本文尝试在无紫外方案中评估真空能量对暗能量的贡献。结果表明,这不是紫外区域场的问题,而是重场贡献被抑制的问题。然后,我们通过尺度去耦方法探索了有效描述。参数空间表明,活动中微子场的真空能量可以自然满足暗能量密度的观测,并预期一种典型质量约为10 meV(10^{-3} eV)的中微子。自然性偏好正常排列的中微子,暗能量设定的中微子质量窗口为6.3 meV ≤ m₁ ≤ 16.3 meV,10.7 meV ≤ m₂ ≤ 18.4 meV,50.5 meV ≤ m₃ ≤ 52.7 meV。

英文摘要:

The quartic-divergent vacuum energy poses an ultraviolet (UV) challenge (the cosmological constant problem) in probing the nature of dark energy. Here we try to evaluate the contribution of the vacuum energy to dark energy in the UV-free scheme. The result indicates that it is not a problem of a field in the UV region but a question of the contributions of heavy fields being suppressed. Then, we explore an effective description via scale decoupling. The parameter spaces suggest that the vacuum energy of active neutrino fields can naturally meet the observation of dark energy density, and a neutrino with a typical mass $\sim$ 10 meV $(10^{-3}$ eV) is expected. The normal ordering neutrinos are preferred by naturalness, and the neutrino mass window set by dark energy is 6.3 meV $\lesssim m_1 \lesssim$ 16.3 meV, 10.7 meV $\lesssim m_2 \lesssim$ 18.4 meV, 50.5 meV $\lesssim m_3 \lesssim$ 52.7 meV.
