Cottingham formula and the pion electromagnetic mass difference at finite temperature
We generalize the Cottingham formula at finite (T 6= 0) temperature by using the imaginary time formalism. The Cottingham formula gives the theoretical framework to compute the electromagnetic mass differences of the hadrons using a dispersion relation approach. It can be also used in other contexts, such as non leptonic weak decays, and its generalization to finite temperature might be useful ...
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 کاملThe Electromagnetic Mass Difference of Pions at Low Temperature
We compute low temperature corrections to the electromagnetic mass difference of pions in the chiral limit. The computation is done in a model independent way in the framework of chiral perturbation theory, using the background field method and the hard thermal loop approximation. We also generalize at low temperature the sum rule of Das et al. We find that the mass difference between the charg...
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...
