The QCD trace anomaly
Jens O. Andersen, Lars E. Leganger, Michael Strickland +1
In this brief report we compare the predictions of a recent next-to-next-to-leading order hard-thermal-loop perturbation theory (HTLpt) calculation of the QCD trace anomaly to avai…
Three-loop HTL QCD thermodynamics
Jens O. Andersen, Lars E. Leganger, Michael Strickland +1
The hard-thermal-loop perturbation theory (HTLpt) framework is used to calculate the thermodynamic functions of a quark-gluon plasma to three-loop order. This is the highest order…
Kaon condensation in CFL quark matter, the Goldstone theorem, and the 2PI Hartree approximation
Lars E. Leganger
At very high densities, QCD is in the color-flavor-locked phase, which is a color-superconducting phase. The diquark condensates break chiral symmetry in the same way as it is brok…
Hard-thermal-loop QCD Thermodynamics
Michael Strickland, Jens O. Andersen, Lars E. Leganger +1
Naively resummed perturbative approximations to the thermodynamic functions of QCD do not converge at phenomenologically relevant temperatures. Here we review recent results of a t…
NNLO hard-thermal-loop thermodynamics for QCD
Jens O. Andersen, Lars E. Leganger, Michael Strickland +1
We calculate the thermodynamic functions of a quark-gluon plasma for general N_c and N_f to three-loop order using hard-thermal-loop perturbation theory. At this order, all the ult…
Non-factorizable contribtion to
Lars E. Leganger, Jan O. Eeg
The decay modes of the type are dynamically different. For the case there is a substantial factorized contribution which dominates. In…
