We consider general relativity as a limit case of the scalar–tensor theory with Barbero–Immirzi (BI) field when the field tends to a constant. We use Shapiro time delay experimental value of 1 / w ( x ) = ( 2 . 1 ± 2 . 3 ) 1 0 − 5 provided by the Cassini spacecraft to find the present BI parameter value.

来自实验的 Barbero-Immirzi 值
当场趋于常数时,我们将广义相对论视为具有 Barbero-Immirzi (BI) 场的标量张量理论的极限情况。我们使用夏皮罗时间延迟实验值1 / w ( X ) = ( 2 . 1 ± 2 . 3 ) 1 0 - 5 由卡西尼号宇宙飞船提供,以找到当前的 BI 参数值。
