In this framework, both the chiral symmetry breaking and linear …

Nettet11. apr. 2024 · In this study, we discuss how iterative solutions of QCD-inspired gap-equations at the finite chemical potential demonstrate domains of chaotic behavior as well as non-chaotic domains, which represent one or the other of the only two—usually distinct—positive mass gap solutions with broken or restored chiral symmetry, … Nettet24. apr. 2006 · Later the SW model became a popular AdS/QCD approach to modeling the non-perturbative strong interactions -the hadron Regge spectroscopy, hadron form-factors, distribution amplitudes, QCD... NettetThere are two methods to solve QCD; one is “lattice QCD” [ 1] and the other is “AdS/QCD.” The formulation of lattice QCD is based on discretization of spacetime and it requires high performance computing. On the other hand, AdS/QCD is analytic approach and is motivated by the gauge/gravity duality [ 2 – 5 ]. letto lukulaite

NettetAdS/QCD. We expect that the sensible chiral transition behaviors obtained from our model can still be generated somehow from AdS/QCD with dynamical background. In Ref. [82], we proposed an improved soft-wall AdS/ QCD model with linear confinement and spontaneous chiral symmetry breaking in the two-flavor case, where Nettetchiral symmetry breaking. Other approaches in the AdS/ QCD context includes deforming the AdS background as it was done in [14] or the use of a Dp=Dq background with a static quadratic dilaton [15] to induce linear confinement.
