中子星附近电子正电子湮没的Higgs位移
Higgs shifts from electron-positron annihilations near neutron stars
摘要：
我们讨论了潜在的使用中子星，以确定边界上的希格斯-Kretschmann耦合通过寻找在伽玛射线光谱特征的特殊变化。特别是，我们重新分析了GRB 781119中观察到的两个伽玛射线光谱仪检测到的多条线，并推导出一个上限的Higgs-Kretschmann耦合，这是比最近从白矮星得到的约束。这就需要对最近观测站的伽马射线暴光谱进行有针对性的分析，专门寻找致密源附近电子-正电子和质子-反质子湮灭光谱的差分位移，以及来自同一中子星的电子和质子回旋加速器线信号。
英文摘要：
We discuss the potential for using neutron stars to determine bounds on the Higgs-Kretschmann coupling by looking at peculiar shifts in gamma-ray spectroscopic features. In particular, we reanalyse multiple lines observed in GRB781119 detected by two gamma-ray spectrometers, and derive an upper bound on the Higgs-Kretschmann coupling that is much more constraining than the one recently obtained from white dwarfs. This calls for targeted analyses of spectra of gamma-ray bursts from more recent observatories, dedicated searches for differential shifts on electron-positron and proton-antiproton annihilation spectra in proximity of compact sources, and signals of electron and proton cyclotron lines from the same neutron star.
