Future directions and challenges of photon quality research in 6.

Research Trend of Combination of 6.1 Theory and Experiment

At the forefront of photon quality research, the deep integration of theory and experiment has become a significant trend. Theoretical physicists are working to build more sophisticated quantum field theory models to explain the possible mass generation mechanisms of photons, and these models need to be rigorously compared with experimental data. For example, string theory and supersymmetry theory offer 1 possible explanations for photon mass, but the predictions of these the......
