Physicists Set Record Precision for the Strong Coupling Constant

An international team led in part by Trinity College Dublin has delivered the most precise measurement yet of the strong coupling constant, which governs quark-gluon interactions. The result halves the combined error of previous experiments and sets a new benchmark for tests of the Standard Model.
