Electromagnetic vertex function of the pion at T > 0
The matrix element of the electromagnetic current between pion states is calculated in quenched lattice QCD at a temperature of T = 0.93 T c. The nonperturbatively improved Sheikholeslami-Wohlert action is used together with the corresponding O(a) improved vector current. The electromagnetic vertex function is extracted for pion masses down to 360 MeV and momentum transfers Q 2 ≤ 2.7 GeV
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 کاملPion Loop Contribution to the Electromagnetic Pion Charge Radius
A phenomenological Dyson-Schwinger equation approach to QCD, formalised in terms of a QCD based model field theory, is used to calculate the electromagnetic charge radius of the pion. The contributions from the quark core and pion loop, as defined in this approach, are identified and compared. It is shown explicitly that the divergence of the charge radius in the chiral limit is due to the pion...
متن کاملElectromagnetic Corrections to Charged Pion Scattering at Low Energies
The electromagnetic corrections to the low energy scattering amplitude involving charged pions only are investigated at leading and next-to-leading orders in the twoflavour chiral expansion. As an application, the corresponding variation in the strong 2S − 2P level shift is evaluated. The relative variation is of the order of 5%.
