Goldstone bosons at non-zero temperature
Peter Lowdon, Owe Philipsen
Spontaneous symmetry breaking in quantum field theories at non-zero temperature still holds fundamental open questions, in particular what happens to vacuum Goldstone bosons when t…
Spectral properties of pseudo-scalar mesons through the QCD chiral crossover
Peter Lowdon, Owe Philipsen
We summarise recent progress towards the non-perturbative determination of thermal spectral functions for pseudo-scalar mesons in QCD by exploiting constraints imposed by micro-cau…
Non-perturbative constraints on perturbation theory at finite temperature
Peter Lowdon, Owe Philipsen
It has long been understood that the inclusion of temperature in the perturbative treatment of quantum field theories leads to complications that are not present at zero temperatur…
On the (in)consistency of perturbation theory at finite temperature
Peter Lowdon, Owe Philipsen
A well-known difficulty of perturbative approaches to quantum field theory at finite temperature is the necessity to address theoretical constraints that are not present in the vac…
Pseudo-scalar meson spectral properties in the chiral crossover region of QCD
Dibyendu Bala, Olaf Kaczmarek, Peter Lowdon +2
Determining the type of excitations that can exist in a thermal medium is key to understanding how hadronic matter behaves at extreme temperatures. In this work we study this quest…
On chiral spin symmetry and the QCD phase diagram
Owe Philipsen, Leonid Ya. Glozman, Peter Lowdon +1
Recently, an approximate chiral spin-flavour symmetry was observed in multiplet patterns of QCD meson correlation functions, in a temperature range above the chiral crossov…
