轨道电子俘获中洛伦兹不变性的检验

Testing Lorentz invariance in orbital electron capture

K. K. Vos, H. W. Wilschut, R. G. E. Timmermans

摘要:

洛伦兹破坏的计算最近被扩展到弱扇区,特别是中子和核$β$衰变[1]。从禁戒$β$ -衰变跃迁的实验中,在$10^{-6}$ - $10^{-8}$的范围内,得到了$W$ -玻色子传播子的洛伦兹破坏分量的强极限[2]。为了改善这些限制,必须考虑强源。在这份简要报告中,我们研究了经历轨道电子捕获并允许在高衰变率和低剂量下进行实验的同位素。我们推导了洛伦兹破坏微分衰减率的表达式,并讨论了竞争性实验的选择及其所需的精度。

英文摘要:

Searches for Lorentz violation were recently extended to the weak sector, in particular neutron and nuclear $β$ decay [1]. From experiments on forbidden $β$-decay transitions strong limits in the range of $10^{-6}$-$10^{-8}$ were obtained on Lorentz-violating components of the $W$-boson propagator [2]. In order to improve on these limits strong sources have to be considered. In this Brief Report we study isotopes that undergo orbital electron capture and allow experiments at high decay rates and low dose. We derive the expressions for the Lorentz-violating differential decay rate and discuss the options for competitive experiments and their required precision.
