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…
Evidence for CP violation in decays
LHCb collaboration, R. Aaij, B. Adeva +698
Three-body and decays are studied using a data sample corresponding to an integrated luminosity of 3.0 collected by…
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…
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…
