Relevant energy scale of color confinement from lattice QCD

Understand

We propose a new lattice framework to extract the relevant gluonic energy scale of QCD phenomena which is based on a "cut" on link variables in momentum space.

• This framework is expected to be broadly applicable to all lattice QCD calculations.
• Using this framework, we quantitatively determine the relevant energy scale of color confinement, through the analyses of the quark-antiquark potential and meson masses.
• The relevant energy scale of color confinement is found to be below 1.5 GeV in the Landau gauge.
