Pion decay constant at finite temperature in the nonlinear sigma model.
نویسندگان
چکیده
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.

Relating 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 کاملSigma-term physics in the perturbative chiral quark model
We apply the perturbative chiral quark model (PCQM) at one loop to analyse meson-baryon sigma-terms. Analytic expressions for these quantities are obtained in terms of fundamental parameters of low-energy pion-nucleon physics (weak pion decay constant, axial nucleon coupling, strong pion-nucleon form factor) and of only one model parameter (radius of the nucleonic three-quark core). Our result ...
متن کاملChiral Ward identities and pion propagation at finite temperature in the linear sigma model
Working within the linear sigma model at finite temperature, we construct effective one-loop vertices and propagators satisfying the chiral Ward identities, for small pion momentum and mass compared to the sigma mass. We obtain an expansion for the pion dispersion relation up to second order in the parameter mπ/4π f π. At leading order, this expansion reproduces the dispersion curve obtained in...
متن کاملFinite-temperature corrections in the dilated chiral quark model.
We calculate the finite-temperature corrections in the dilated chiral quark model using the effective potential formalism. Assuming that the dilaton limit is applicable at some short length scale, we interpret the results to represent the behavior of hadrons in dense and hot matter. We obtain the scaling law, fπ(T ) fπ = mQ(T ) mQ ≃ mσ(T ) mσ while we argue, using PCAC, that pion mass does not ...
متن کاملChiral quark model with infrared cut - off for the description of meson properties in hot matter
A simple chiral quark model of the Nambu–Jona-Lasinio (NJL) type with a quark confinement mechanism is constructed for the description of the light meson sector of QCD at finite temperature. Unphysical quark production thresholds in the NJL model are excluded by an infrared cutoff in the momentum integration within quark loop diagrams. This chiral quark model satisfies the low energy theorems. ...
