# Elimination of the Landau ghost from chiral solitons.

@article{Hartmann1994EliminationOT, title={Elimination of the Landau ghost from chiral solitons.}, author={Hartmann and Beck and Bentz}, journal={Physical review. C, Nuclear physics}, year={1994}, volume={50 6}, pages={ 3088-3093 } }

We show a practical way based on the Kaellen-Lehmann representation for the two-point functions to eliminate the instability of the vacuum against formation of small sized meson configurations in the chiral [sigma] model.

Properties of predictive formulation of the Nambu–Jona–Lasinio model and the ghost problem

- Physics
- 2009

Recently proposed by Battistel et al, 'predictive formulation of the NJL model' is discussed and its connection with the differential regularization is noted. The principal problem of this…

Searching for Quantum Solitons in a 3+1 Dimensional Chiral Yukawa Model

- Physics
- 2002

Abstract We search for static solitons stabilized by heavy fermions in a (3+1)-dimensional Yukawa model. We compute the renormalized energy functional, including the exact one-loop quantum…

Casimir Energies in the Light of Renormalizable Quantum Field Theories

- Physics
- 2003

Effective hadron models commonly require the computation of functional determinants. In the static case these are one‐loop vacuum polarization energies, known as Casimir energies. In this talk I will…

Searching for Novel Objects in the Electroweak Theory

- Physics
- 2004

We explore the Higgs-Gauge configuration space in the standard electroweak theory. We outline a general prescription that uses the non-trivial topology associated with the gauge group of the theory,…

Gauge invariance and vacuum energies of non-Abelian string-configurations

- Physics
- 2010

Abstract We improve on a method to compute the fermion contribution to the vacuum polarization energy of string-like configurations in a non-Abelian gauge theory. We establish the new method by…

Heavy Fermion Quantum Effects in SU(2)L Gauge Theory

- Physics
- 2003

Abstract We explore the effects of a heavy fermion doublet in a simplified version of the standard electroweak theory. We integrate out the doublet and compute the exact effective energy functional…

Quantum Stabilization of Cosmic Strings

- Physics
- 2015

In the standard model, stabilization of a classically unstable cosmic string may occur through the quantum fluctuations of a heavy fermion doublet. We review numerical results from a semiclassical…

Mean-Field Expansion, Regularization Issue, and Multi-Quark Functions in Nambu-Jona-Lasinio Model

- Computer Science, MathematicsSymmetry
- 2019

The results of the investigation of multi-quark equations in the Nambu–Jona-Lasinio (NJL) model in the mean-field expansion are presented and so-called “predictive regularization” in the NJL model is discussed, and a modification of this regularization, which is free of the Landau pole, is proposed.
