The Bloch-nordsieck Propagator at Finite Temperature
We have shown recently that the resummation of soft photon contributions leads to a non-exponential decay of the fermion excitations in hot QED plasmas. The retarded propagator of a massless fermion was found to behave as SR(t 1/gT ) ∼ exp{−αTt [ lnωpt+C]}, where ωp = gT/3 is the plasma frequency, α = g2/4π, and C is a constant, independent of g, which was left undefined. This term is computed ...
متن کاملBloch - Nordsieck Thermometers : One - loop Exponentiation in Finite Temperature QED
We study the scattering of hard external particles in a heat bath in a real-time formalism for finite temperature QED. We investigate the distribution of the 4-momentum difference of initial and final hard particles in a fully covariant manner when the scale of the process, Q, is much larger than the temperature, T. Our computations are valid for all T subject to this constraint. We exponentiat...
متن کاملStructure of the gluon propagator at finite temperature
The thermal self-energy of gluons generally depends on four Lorentz-invariant functions. Only two of these occur in the hard thermal loop approximation of Braaten and Pisarski because of the abelian Ward identity KμΠ μν htl = 0. However, for the exact self-energy KμΠ μν 6= 0. In linear gauges the SlavnovTaylor identity is shown to require a non-linear relation among three of the Lorentz-invaria...
متن کاملBloch oscillations at room temperature.
We report on the observation of coherent electronic wave-packet oscillations in a semiconductor heterostructure at room temperature. Bloch oscillations are excited in a wide-miniband GaAs/Al0.3GaO.7As superlattice by femtosecond laser pulses. Several cycles of the coherent electronic motion are observed within the dephasing time of the intraband polarization. The frequency can be tuned by the a...
متن کاملTotal Cross-sections and Bloch-Nordsieck Gluon Resummation
Physics Department and INFN, University of Perugia, Perugia, Italy (Received October 26, 2004) The physics underlying the fall and eventual rise in various total crosssections at high energies has been investigated over a decade using a model based on the Bloch–Nordsieck resummation in QCD. Here a brief review of our latest results is presented and comparison made with experimental data on pp, ...
