Remarks on "The Modification of Feynman Diagrams in Curved Space-Time"
Abstract
The arXiv preprint 2411.15164v1 Li:2024ltx discusses how a weak Schwarzschild spacetime modifies Feynman diagram calculations and the governing equations of scalar and spinor particles. This short review offers an extended analysis on concerning points involving massless particles and limitations of weak-field approximation. Written for the Universit\"at Potsdam lecture New Developments in Astrophysics, Winter Semester 2024/25.
