As far as i know particle accelerators are the main tools in particle physics for investigating fundamental physics. Is it possible to perform tabletop experiments, like in low energy physics lab, without using colliders for finding new physics beyond the Standard Model?
I heard that some precise measurements can do what I am asking, but how and is it reliable?
Edit: i mean experiments on lab, where there is in principle the control of the source, that doesn't involve astroparticles. I prefer to leave this in another question.
