L. Maisenbacher et al, Sub-part-per-trillion test of the Standard Model with atomic hydrogen, Nature, February 11, 2026, DOI: 10.1038/s41586-026-10124-3, https://doi.org/10.1038/s41586-026-10124-3 ...
No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...
For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...
