Question for physicists: Are the G-2 results more groundbreaking than discovering the Higgs particle to moving physics forward?
- peteradio 6y agoIf physics is climbing a mountain. G-2 result is seeing the next hand hold (hoping its not a mirage). Higgs discovery and its subsequent precision measurement is resting your toe into a hold and flexing your calf upwards.
- Diederich 6y agoI'm not a physicist, I just pay some attention to these things. The Higgs particle was expected, and so finding it within expected ranges was confirmation of the standard model. The G-2 results are showing deviations from the expected ranges from the standard model. In the former case, Higgs, the standard was further, strongly confirmed. In the latter case, G-2, there's a strong indication that the standard model is fundamentally missing something. I think that's pretty exciting!
- quantum_mcts 6y agoPhysicist. Some people in the community are quite excited because it hints at something beyond SM. The problem is that the quoted theoretical prediction for g-2 is not a settled issue and is a subject of a long controversy between various groups of theorists. https://physics.stackexchange.com/a/627852/386 https://physics.stackexchange.com/a/627852/386
- podiki 6y agoI would agree with the other commenters. g-2 has been a debate for a long time, but fundamentally points to something new if the result holds. The Higgs was expected, and given the mass and properties we've seen, doesn't point to anything new. "New" meaning not the Standard Model.
