Here, we report on recent experimental and theoretical developments in our understanding of the QCD running coupling αs in QCD’s nonperturbative regime. They allow us to analytically compute the hadron mass spectrum, with Λs the only input necessary to this determination. The computed spectra agrees well with experimental data.
