A recent Nature publication has determined the strong coupling constant αs to five parts per mille using only low-energy lattice QCD input, addressing a key theoretical bottleneck for HL-LHC and future Higgs factory precision predictions.
Scientists have developed the world's most accurate atomic clock, setting a new standard for precision timekeeping technology.
A team led by Ignazio Ciufolini used the LARES-2 satellite to measure Earth's frame dragging effect with unprecedented precision (0.2% uncertainty), providing the most accurate test yet of Einstein's general theory of relativity.
