The quest for light scalar quarkonia from an N f = 3 linear sigma model with vectors and axial - vectors
We address the question whether it is possible to interpret the low-lying scalar mesons f 0 (600) and a 0 (980) as ¯ qq states within a U(3) × U(3) Linear Sigma Model containing vector and axial-vector degrees of freedom. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

We discuss the role of the axial U(1)A symmetry in the chiral phase transition using the U(Nf )R× U(Nf )L linear sigma model with two massless quark flavors. We expect that above a certain temperature the axial U(1)A symmetry will be effectively restored as well as SU(Nf )R×SU(Nf )L. Then we can construct a string-like static solution of the η string and a kink-like classical solution of the do...
متن کاملSupersymmetric black rings and non-linear sigma models
In this paper we investigate the non-linear sigma model arising in the reduction of D = 5 supergravity to D = 3, and present the application of this sigma model to supersymmetric black ring solutions in five-dimensional minimal supergravity. With the ansatz of stationary solutions with R×U(1)×U(1) isometry, we obtain a two-dimensional Lagrangian corresponding to geodesic motion of a string-like...
متن کاملNoncommutative Linear Sigma Models
We examine noncommutative linear sigma models with U (N) global symmetry groups at the one-loop quantum level, and contrast the results with our previous study of the noncommutative O(N) linear sigma models where we have shown that Nambu-Goldstone symmetry realization is inconsistent with continuum renormaliza-tion. Specifically we find no violation of Goldstone's theorem at one-loop for the U ...
متن کاملNoncommutative U(1) Gauge Theory as a Non-linear Sigma Model
Noncommutative U (1) gauge theory in 4−dimensions is shown to be equivalent in some scaling limit to an ordinary non-linear sigma model in 2−dimensions. The model in this regime is solvable and the corresponding exact beta function is found. We also show that classical U (n) gauge theory on R d−2 ×R 2 θ can be approximated by a sequence of ordinary (d − 2)−dimensional Georgi-Glashow models with...
