The quark-mass dependence of the potential energy between static colour sources in the QCD vacuum with light and strange quarks

Bulava, John; Knechtli, Francesco; Koch, Vanessa; Morningstar, Colin; Peardon, Michael (July 2024, Physics Letters B)

The low-lying energy spectrum of the static-colour-source-anti-source system in a vacuum containing light and strange quarks is computed using lattice QCD for a range of different light quark masses. The resulting levels are described using a simple model Hamiltonian and the parameters in this model are extrapolated to the physical light-quark masses. In this framework, the QCD string tension is found to be sqrt(sigma) = 445(3)_stat (6)_sys MeV.
