QED at Finite Temperature and Density: Renormalization in hot and dense medium, effective parameters of Quantum Electrodynamics,,Used
Delivery time: 8-12 business days (International)
Renormalization and radiative corrections in QED are studied at finite temperature and density. We use the FermiDirac and BoseEinestein distribution functions in a realtime formalism to generalize the calculations of the electron mass, wavefunction and charge renormalization constants, at high temperatures and chemical potentials. Further, the radiative corrections to the decay rate of a neutral scalar particle H ? e?e? and the leptonic decay of Z boson are reexamined at high temperatures and chemical potentials. Renormalization constants of QED are calculated for > T and T> in the limit T?0 and
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
