Pion decay constant at finite temperature in the nonlinear sigma model.
We calculate the pion decay constant near the critical temperature of the O(N) nonlinear sigma model in the large N limit. Making use of the known low temperature behavior, we construct a Padé approximant to obtain the behavior of fπ(T ) at all temperatures.
متن کاملRelating the pion decay constant to the chiral restoration temperature
Relating the pion decay constant to the chiral restoration temperature. Abstract We review the relationship between the pion decay constant f π , the chiral symmetry restoration temperature T c and the phenomenology of low energy chiral symmetry breaking in view of the recent confirmation of the existence of a sigma meson with a mass of 600-700 MeV.
متن کاملPion mass and decay constant
Independent of assumptions about the form of the quark-antiquark scattering kernel we derive the explicit relation between the pion Bethe-Salpeter amplitude, Γπ, and the quark propagator in the chiral limit; Γπ necessarily involves a non-negligible γ5γ · P term (P is the pion four-momentum). We also obtain exact expressions for the pion decay constant, fπ, and mass, both of which depend on Γπ; ...
متن کاملPion-Nucleon Coupling at Finite Temperature
The pion nucleon vertex function at finite temperature is studied in the framework of: (a) the thermal (linear) sigma model to leading (one-loop) order, and (b) a thermal QCD-Finite Energy Sum Rule. Results from both methods indicate that the strength of the pion-nucleon coupling decreases with increasing T , vanishing at a critical temperature. The associated mean-square radius is a monotonica...
متن کاملPion electromagnetic form factor at finite temperature.
Temperature effects on the electromagnetic couplings of pions in hot hadronic matter are studied with an effective chiral Lagrangian. We show that the Ward-Takahashi identity is satisfied at non-zero temperature in the soft pion limit. The in-medium electromagnetic form factor of the pion is obtained in the time-like region and shown to be reduced in magnitude, especially near the vector-meson ...
