The quasiparticle structure of hot gauge theories
Edmond Iancu, Service de Physique Theorique, Saclay +1
The study of the ultrarelativistic plasmas in perturbation theory is plagued with infrared divergences which are not eliminated by the screening corrections. They affect, in partic…
Lifetime of quasiparticles in hot gauge theories
Edmond Iancu, Service de Physique Theorique, Saclay +1
The perturbative calculation of the lifetime of charged excitations in ultrarelativistic plasmas is plagued with infrared divergences which are not eliminated by the screening corr…
High Temperature QCD
Edmond Iancu
I discuss finite-temperature gauge theories as a framework to describe the quark-gluon plasma in the regime of high temperature where the gauge coupling is small, . I revie…
Lifetimes of quasiparticles and collective excitations in hot QED plasmas
Jean-Paul Blaizot, Edmond Iancu
The perturbative calculation of the lifetime of fermion excitations in a QED plasma at high temperature is plagued with infrared divergences which are not eliminated by the screeni…
Lifetime of quasiparticles in hot QED plasmas
Jean-Paul Blaizot, Edmond Iancu
The calculation of the lifetime of quasiparticles in a QED plasma at high temperature remains plagued with infrared divergences, even after one has taken into account the screening…
