Abstract

Electromagnetic splittings for hadrons are calculated in a formalism where the constituent quarks are considered as dressed quasiparticles. The electromagnetic interaction, which contains coulomb, contact and hyperfine terms, is folded with the quark electrical density. The strong potential is a modification of the well known funnel potential. Our model contains only one free parameter and the agreement with experimental data is reasonable although it seems very difficult to obtain a perfect description in any case. [ABSTRACT FROM AUTHOR]

Subjects
RENORMALIZATION (Physics), QUANTUM field theory, ATOMS, MOLECULES, NUCLEAR physics, PHYSICS
Abstract

Examines the regularization method for the singular attractive 1/r4 potential, which describes the long range part of the polarizability potential in atomic and molecular systems. Determination of the short range part of the potential by a regularization procedure; Derivation of the renormalization group flow equation; Significance of the observables characterized by small energies on the consistency of the regularization method.
