Current quark

Current quarks (also called naked quarks or bare quarks) are defined as the constituent quark cores (constituent quarks with no covering) of a valence quark.:150–151 Current quarks (also called naked quarks or bare quarks) are defined as the constituent quark cores (constituent quarks with no covering) of a valence quark.:150–151 If, in one constituent quark, the current quark is hit inside the covering with large force, it accelerates through the covering and leaves it behind. In addition, current quarks possess one asymptotic freedom within the perturbation theory described limits. In quantum chromodynamics, the mass of the current quarks carries the designation current quark mass. The local term plays no more role for the description of the hadrons with the light current quarks.In the MS ¯ {displaystyle {overline { ext{MS}}}} -Scheme at μ = {displaystyle mu =} 2 GeV/c2 the quark masses are: A description is only possible with the help of relativistic quantum mechanics. The current quark mass is also called the mass of the 'naked' quarks.The mass of the current quark is reduced by the term of the constituent quark covering mass. The current quark mass is a logical consequence of the mathematical formalism of the quantum field theory (QFT), thus it is from a not descriptive origin.The current quark masses of the light current quarks are much smaller than the constituent quark masses. Reason for this is the missing of the mass of the constituent quark covering.
