Renormalization of an effective Light-Cone QCD-inspired theory for the Pion and other Mesons
نویسندگان
چکیده
The renormalization of the effective QCD-Hamiltonian theory for the quarkantiquark channel is performed in terms of a renormalized or fixed-point Hamiltonian that leads to subtracted dynamical equations. The fixed pointHamiltonian brings the renormalization conditions as well as the counterterms that render the theory finite. The approach is renormalization group invariant. The parameters of the renormalized effective QCD-Hamiltonian comes from the pion mass and radius, for a given constituent quark mass. The 1s and excited 2s states of uq are calculated as a function of the mass of the quark q being s, c or b, and compared to the experimental values. Typeset using REVTEX 1

On the Effective Light-cone Qcd-hamiltonian
Taking the effective interaction between a quark and an anti-quark from previous work, the dependendence on a regularization scale is removed in line with the renormalization group. In order to emphasize the essential point, the full spinor interaction is replaced by a model which includes only the Coulomb and the hyperfine interaction. By adjusting the effective quark masses, the only free par...
متن کاملFirst successful renormalization of a QCD-inspired Hamiltonian
Abstract The long standing problem of non perturbative renormalization of a gauge field theoretical Hamiltonian is addressed and explicitly carried out within an (effective) light-cone Hamiltonian approach to QCD. The procedure is in line with the conventional ideas: The Hamiltonian is first regulated by suitable cut-off functions, and subsequently renormalized by suitable counter terms to make...
متن کاملPreprint MPIH-V16-1999 Estimates of the physical meson masses by an effective light-cone Hamiltonian
A recent renormalization group analysis of the effective light-cone Hamiltonian yields 5 flavor masses and 2 mass shifts as free parameters. These are determined in the present note and used to calculate the masses of all 30 physical mesons (The topped mesons have been omitted). The agreement between experiment and theoretical estimate is quite satisfactory over the whole dynamical range, from ...

متن کاملOn the effective light-cone QCD-Hamiltonian: Application to the pion and other mesons
The light-cone approach [1] to the bound-state problem in gauge theory [2] aims at solving HLC |Ψ〉 = M2|Ψ〉. If one disregards possible zero modes [4] and works in the light-cone gauge, the (light-cone) Hamiltonian HLC is given as a Fock-space operator in [2], or in the compendium [3]. Its eigenvalues are the invariant mass-squares M of physical particles associated with the eigenstates |Ψ〉. In ...
