AI总结:

研究库仑相互作用对β衰变杂质中探测残余中微子的影响,分析介电间隔抑制杂化和扰动理论中最低非平凡阶的杂化效应。

摘要:

测量电子中微子质量是长期目标,需要β衰变实验的高能量分辨率和可见的宇宙中微子背景(CνB)谱。许多量子力学和化学效应可能损害所需分辨率/可见性,例如β衰变杂质中的电子与固态环境中的电子之间的库仑相互作用。我们分析当使用介电间隔完全抑制杂化时的影响,以及当杂化存在到扰动理论中最低非平凡阶时的影响。

英文摘要:

Measuring the electron neutrino mass is a long-standing objective and requires a high energy resolution of certain $β$-decay experiments, as well as a visible cosmic neutrino background (C$ν$B) spectrum. Many quantum mechanical and chemical effects could potentially impair the required resolution/visibility, e.g., the Coulomb interactions between the electrons in the $β$-decaying impurity and in the solid-state environment. We analyze the effect when hybridization is suppressed completely using a dielectric spacer, and also when hybridization is present up to the lowest nontrivial order in perturbation theory.
