Quark masses in a BCS-like approach using\(Q\bar Q\) potentials

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Using a BCS like equation we have computed constituent quark masses as a function of a parameterC. This parameter is a measure of the effective strength of the interaction for off-the-mass-shell, localised\(q\bar q\) pairs and is given byC=R/E, whereE is the energy required to separate the pair to a distanceR. Several phenomenological flavour independent\(q\bar q\) potentials and correlation functions yield results similar in nature. Predictions for distribution functions of intrinsic sea quarks have been made.
