从CERN到GRAN-SASSO实验室地球内部通向广义相对论度规的道路及其对中微子旅行的影响
The road toward a general relativistic metric inside the Earth and its effect on neutrino travel from CERN to GRAN-SASSO Laboratory
摘要：
在第一次尝试描述广义相对论对地球内部中微子运动的影响时，我们忽略了地球自转、地球椭圆率和地表地形的变化，而把注意力集中在地球物理模型如PREM对地球内部密度的描述上。假设地球不旋转，广义相对论效应对中微子从CERN到GRAN-SASSO的传播产生了$δt=4.1863 \, picosecond$的延迟。
英文摘要：
In a first attempt to describe the effect on neutrino travel inside the Earth caused by general relativity in the case of a dense Earth, we have neglected the Earth's rotation, the Earth's ellipticity and also the surface terrain variation, nevertheless we have focused our attention on the density description of the Earth interior provided by geophysic's models such as PREM. Assuming a non rotating Earth, the general relativistic effect on neutrino travelling from CERN to GRAN-SASSO happened to produce a delay of $δt=4.1863 \, picosecond$.
