Title: A soft-wall dilaton

Abstract

Here, we study the properties of the dilaton in a soft-wall background using two solutions of the Einstein equations. These solutions contain an asymptotically AdS metric with a nontrivial scalar profile that causes both the spontaneous breaking of conformal invariance and the generation of a mass gap in the particle spectrum. We first present an analytic solution, using the superpotential method, that describes a CFT spontaneously broken by a finite dimensional operator in which a light dilaton mode appears in the spectrum. This represents a tuning in the vanishing of the quartic coupling in the effective potential that could be naturally realised from an underlying supersymmetry. Instead, by considering a generalised analytic scalar bulk potential that quickly transitions at the condensate scale from a walking coupling in the UV to an order-one β-function in the IR, we obtain a naturally light dilaton. This provides a simple example for obtaining a naturally light dilaton from nearly-marginal CFT deformations in the more realistic case of a soft-wall background.

Soft supersymmetry breaking on the brane

Journal Article Brax, Ph ; Chatillon, N - Physical Review. D, Particles Fields

We consider the low-energy description of 5D models of supergravity with boundaries comprizing a vector multiplet and the universal hypermultiplet in the bulk. We analyze the spontaneous breaking of supersymmetry induced by the vacuum expectation value of superpotentials on the boundary branes. When supersymmetry is broken, the moduli corresponding to the radion, the zero mode of the vector multiplet scalar field and the dilaton develop a potential in the effective action. We compute the resulting soft breaking terms and give some indications on the features of the corresponding particle spectrum. We consider some of the possible phenomenological implications when supersymmetrymore » is broken on the hidden brane.« less

Chiral Symmetry Breaking and Potentials in Soft-Wall Models of AdS/QCD

Journal Article Kapusta, Joseph - AIP Conference Proceedings

The Anti-de Sitter Space/Conformal Field Theory (AdS/CFT) correspondence may offer new and useful insights into the non-perturbative regime of strongly coupled gauge theories such as Quantum Chromodynamics (QCD). A modified soft-wall AdS/QCD model is constructed to incorporate both explicit and spontaneous chiral symmetry breaking and linear confinement. This model contains a modified dilaton and higher-order interaction terms in the Lagrangian. Within this model we calculate the radial scalar, pseudo-scalar, vector and axial-vector mass spectra. We find good agreement with experimental data. We show how to construct potentials which lead to such solutions.

Pseudoscalar mass spectrum in a soft-wall model of AdS/QCD

Journal Article Kelley, Thomas M ; Bartz, Sean P ; Kapusta, Joseph I - Physical Review. D, Particles Fields

The anti-de Sitter space/conformal field theory (AdS/CFT) correspondence may offer new and useful insights into the nonperturbative regime of strongly coupled gauge theories such as quantum chromodynamics (QCD). Recently, a modified soft-wall AdS/QCD model incorporated independent sources for explicit and spontaneous chiral symmetry breaking and linear confinement. This model contains a modified dilaton and higher-order interaction terms in the Lagrangian. Within this model we explore the radial pseudoscalar mass spectrum using two different representations of the pion field. We find the mass eigenvalues associated with each representation show the equivalence between the two, and we find good agreement with themore »« less

Prediction for the mass spectra of resonance mesons in the soft-wall AdS/QCD model with a modified 5D metric

Journal Article Yanqin, Sui ; Yueliang, Wu ; Zhifeng, Xie ; ... - Physical Review. D, Particles Fields

A soft-wall anti-de Sitter/QCD model with a modified five-dimensional metric at the infrared region is constructed to obtain a nontrivial dilaton solution, which incorporates the chiral symmetry breaking and linear confinement. By taking the pion mass and decay constant as two input mass scales, the resulting predictions for the resonance states of pseudoscalar, scalar, vector, and axial-vector mesons agree remarkably with the experimentally confirmed resonance states. The effects of the quartic interaction term are investigated by taking an appropriate sign and magnitude for maintaining the stability of the bulk scalar potential. It is shown that such a simply modified soft-wallmore »« less

Aspects of supersymmetry

Thesis/Dissertation Park, Youngchul

It is shown that string wormholes have the right zero mode structure to generate a superpotential and therefore it is possible to break supersymmetry spontaneously at weak coupling with zero cosmological constant. The c-function for supersymmetric {sigma}-model is calculated. A nontrivial inequality between integrals of powers of Riemann curvature is implied by the c-theorem and it is verified for special cases. The role of supersymmetry on the positivity of energy is studied. A spinorial expression suggested by supersymmetry is used to show that the ADM energy M is positive in two dimensional dilation gravity, a toy model for general relativitymore »« less
