摘要

引力相互作用的影响在粒子物理学中通常被忽略。在费米子的量子力学拉格朗日量中，提出了一个包含引力的一阶公式。可以看出，费米子与引力的最小耦合产生了具有四次相互作用的无扭转有效理论。在穿过热背景后，最常见的扭曲形式有助于中微子的有效质量。该有效质量可以改变电流振荡参数。

Neutrino Oscillation Caused by Spacetime Geometry

Effects of gravitational interaction are generally neglected in particle physics. A first order formulation of gravity is presented to include gravity in Quantum Mechanical Lagrangian of fermions. It is seen that fermions minimally coupled to gravity gives rise to a torsionless effective theory with a quartic interaction. After passing through a thermal background the most generic form of contortion contributes to neutrino effective mass. This effective mass can change the current oscillation parameters.
