Publikováno v: JHEP 05 (2024) 332

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 question for pseudo-scalar mesons comprised of light-strange and strange-st

On chiral spin symmetry and the QCD phase diagram

Autor: Philipsen, Owe, Glozman, Leonid Ya., Lowdon, Peter, Pisarski, Robert D.

Recently, an approximate $SU(4)$ chiral spin-flavour symmetry was observed in multiplet patterns of QCD meson correlation functions, in a temperature range above the chiral crossover. This symmetry is larger than the chiral symmetry of massless QCD,

Real-time observables from Euclidean thermal correlation functions

Autor: Lowdon, Peter, Tripolt, Ralf-Arno

Publikováno v: Phys. Rev. D 106, 056006 (2022)

In this work we apply a local quantum field theory approach in order to analyse the connection between real-time observables and Euclidean thermal correlation functions. In particular, using data generated from the functional renormalisation group in

Non-perturbative BRST symmetry and the spectral structure of the ghost propagator

Autor: Li, Shirley Weishi, Lowdon, Peter, Oliveira, Orlando, Silva, Paulo J.

Publikováno v: Phys. Lett. B 823 (2021) 136753

In BRST-quantised Yang-Mills theory the existence of BRST symmetry imposes significant constraints on the analytic structure of the continuum theory. In particular, the presence of this symmetry in the non-perturbative regime implies that any on-shel
