- 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.[1]
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:
Current quark Mass Δx Up quark 5–10 MeV/c2 20–40 fm Down quark 5–10 MeV/c2 20–40 fm Strange quark Charm quark Bottom quark Top quark A description is only possible with the help of relativistic quantum mechanics.
