在GSI电子俘获测量中的中微子磁矩效应

Neutrino magnetic moment effects in electron-capture measurements at GSI

Avraham Gal

摘要:

我猜想,GSI的类氢重离子两体电子俘获衰变的单离子测量中所报道的时间调制衰变率可能与储存环静态磁场中的中微子自旋进动有关。这些“GSI振荡”产生于磁场内外衰变幅度之间的干扰,这种情况需要狄拉克中微子的磁矩比Borexino太阳中微子上限0.54 x 10 E(-10)玻尔磁子低六倍。我还以一种以前没有讨论过的方式表明,与大质量中微子振幅之间的干扰有关的时间调制,如果这种干扰可能出现的话,其周期至少比报道的短四个数量级,并且在给定GSI测量的时间分辨率的情况下,平均值必须为零。

英文摘要:

I conjecture that the time modulated decay rates reported in single ion measurements of two body electron capture decay of hydrogen like heavy ions at GSI may be related to neutrino spin precession in the static magnetic field of the storage ring. These `GSI Oscillations' arise from interference between amplitudes of decay within and without the magnetic field, a scenario that requires a Dirac neutrino magnetic moment six times lower than the Borexino solar neutrino upper limit of 0.54 x 10E(-10) Bohr magneton. I also show in a way not discussed before that the time modulation associated with interference between massive neutrino amplitudes, if such interference could arise, is of a period at least four orders of magnitude shorter than reported and must average to zero given the time resolution of the GSI measurements.
