Most precise measurement of the force that binds nuclear matter achieved

Trinity's Prof.

Stefan Sint, along with collaborators from Germany, Spain and Italy, has published the most precise determination to date of the strong coupling constant.

This parameter governs the interactions between quarks and gluons, the fundamental components of nuclear matter.

The new result halves the error of all previous experimental measurements combined, setting a new benchmark for the Standard Model, which summarizes our current knowledge of elementary particle physics. ...
