Symmetry - Breaking in a σ - Meson Plasma
نویسنده
چکیده
In this brief paper we adress spontaneous symmetry breaking in a finite-temperature scalar meson plasma. We calculate the in-medium averaged thermal σ − σ scattering crossection and the related shear viscosity η(T) and mean-free-path L(T). Our results suggest that slightly below the critical temperature there is a 30 percent peak in the crossection leading to equivalent dips in η(T) and L(T). We discuss the relevance of this observation.

A pr 1 99 8 The RNO framework to the σ - particle mass
The " standard " iso-singlet scalar particle σ is reconsidered in the reduced normal-ordering (RNO) framework to the effective SU(2) theory. Recent reanalysis of the ππ-phase shift [1] is used. 1. There has been a long-standing history of the existence of chiral partner of π-meson, σ-meson [2], or against its existence [3]. The σ-particle is an iso-singlet scalar one, and it is required to exis...
متن کاملLow Lying Scalar Resonances and Chiral Symmetry∗
The σ particle was firstly introduced by Gell-Mann and Levy in association with the linear σ model.1 In such a model, the σ meson develops a non-vanishing vacuum expectation value which triggers the spontaneous breaking of chiral symmetry. Pions act as the (pseudo-)goldstone bosons associated with the spontaneous chiral symmetry breaking (SχSB). In the linear σ model the σ meson fills in the li...
متن کاملSymmetries and Symmetry Breaking *
In understanding the world of matter the introduction of symmetry principles following experimentation or using the predictive power of symmetry principles to guide experimentation is most profound. The conservation of energy, linear momentum, angular momentum, charge, and CPT involve fundamental symmetries. All other conservation laws are valid within a restricted subspace of the four interact...
متن کامل2 00 3 Dynamically Spontaneous Symmetry Breaking and Masses of Lightest Nonet Scalar Mesons as Composite Higgs Bosons
Based on the (approximate) chiral symmetry of QCD Lagrangian and bound state assumption of effective meson fields due to strong interactions of gluons, a nonlinearly realized effective chiral Lagrangian for meson fields is resulted from integrating over the quark fields by using the new finite regularization method. As the new method preserves the symmetry principles of the original theory and ...
