Resonances at finite temperature from the lattice
Jakob Hoffmann, Peter Lowdon, Owe Philipsen
The properties of hadronic resonances at finite temperature constitute an important probe of the thermal QCD medium. In this work we use the concept of thermoparticles, which chara…

Towards a consistent perturbation theory at finite temperature
Passant Ali, Peter Lowdon, Owe Philipsen
The standard approach to perturbation theory for finite-temperature quantum field theories has several issues, including the appearance of ill-defined on-shell contributions in the…

Goldstone bosons across thermal phase transitions
Peter Lowdon, Owe Philipsen
Temperature has a significant effect on the properties of quantum field theories (QFTs) with a spontaneously broken symmetry, in particular on the massless Goldstone bosons that ex…
