Pion-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 ...
متن کاملElectromagnetic pion form factor at finite temperature
The electromagnetic form factor of the pion in the space-like region, and at finite temperature, Fπ(Q 2, T ), is obtained from a QCD Finite Energy Sum Rule. The form factor decreases with increasing T, and vanishes at some critical temperature, where the pion radius diverges. This divergence may be interpreted as a signal for quark deconfinement. John Simon Guggenheim Fellow 1994-1995 The possi...
متن کاملModifications on nucleon parameters at finite temperature
Taking into account the additional operators coming up at finite temperature, we investigate the mass and residue of the nucleon in the framework of thermal QCD sum rules. We observe that the mass and residue of the nucleon are initially insusceptible to the increase of temperature, however, after a certain temperature, they start to fall with increasing the temperature.
متن کاملEffect of Pion-Pion Scattering Resonance on Nucleon Structure and Pion-Nucleon Scattering at Low Energies
The effect of pion-pion scattering resonance on the isovector part of nucleon structure is analysed by a method similar to that of Frazer and Fulco, but with one more subtraction for dispersion relations on helicity amplitudes of nucleon·aritinucleon production process in order to remedy the divergence regarding the left-hand cut. If the subtracted spectral representations are used for the form...
