Comments on compositeness in the SU ( 2 ) linear σ model
First we summarize the quark-level linear σ model compositeness conditions and verify that indeed mσ = 2mq when mπ = 0 and Nc = 3, rather than in the Nc → ∞ limit, as is sometimes suggested. Later we show that this compositeness picture also predicts a chiral symmetry restoration temperature Tc = 2fπ, where fπ is the pion decay constant. We contrast this self-consistent Z = 0 compositeness anal...

15 صفحه اولLinear Σ Model in the Gaussian Functional Approximation
We apply a self-consistent relativistic mean-field variational “Gaussian functional” (or Hartree) approximation to the linear σ model with spontaneously and explicitly broken chiral O(4) symmetry. We set up the self-consistency, or “gap” and the Bethe-Salpeter equations. We check and confirm the chiral Ward-Takahashi identities, among them the Nambu-Goldstone theorem and the (partial) axial cur...
متن کاملDouble Counting Ambiguities in the Linear σ Model
We study the dynamical consequences imposed on effective chiral field theories such as the quark-level SU(2) linear σ model (LσM) due to the fundamental constraints of massless Goldstone pions, the normalization of the pion decay constant and form factor, and the pion charge radius. We discuss quark-level double counting LσM ambiguities in the context of the Salam-Weinberg Z = 0 compositeness c...
