This value is to be used at a scale above the bottom quark mass of about 5 GeV.
The effective quark mass is called constituent quark mass.
It has better described the relationship between quark mass and development of complex organic compounds.
Another unphysical quantity is the quark masses.
They increase in value at lower energy scales, at which the quark masses are generated by the Higgs.
The corresponding quark mass is then predicted.
This model predicts how the electroweak scale may match the top quark mass.
The prevailing view at the time was that the top quark mass would lie in a range of 15 to 26 GeV.
The current quark mass is also called the mass of the 'naked' quarks.
The current quark mass is a parameter to compute sufficiently small color charges.
