Heavy quark thermodynamics with anisotropic lattices
Jon-Ivar Skullerud, Rachel Horohan D'Arcy, Gert Aarts +11
We present recent results from the FASTSUM collaboration, using anisotropic lattice QCD to study spectral properties of heavy quarkonia and open heavy flavour systems at high tempe…
On the effective restoration of symmetry at finite temperature
Gert Aarts, Chris Allton, Ryan Bignell +4
The symmetry of the massless QCD Lagrangian is explicitly broken by the axial anomaly, but it may be effectively restored at finite temperature. Determining the temperatur…
symmetry restoration at finite temperature with mesonic correlators
Ryan Bignell, Gert Aarts, Chris Allton +4
The symmetry of the massless QCD Lagrangian is explicitly broken in the quantised theory by the anomaly. It may be effectively restored at some finite temperature, which w…
The curvature of the pseudo-critical line in the QCD phase diagram from mesonic lattice correlation functions
Antonio Smecca, Gert Aarts, Chris Allton +6
In the QCD phase diagram, the dependence of the pseudo-critical temperature, , on the baryon chemical potential, , is of fundamental interest. The variation of $…
Hybrid Charmonium at Finite Temperature
Juan Andrés Urrea-Niño, Ryan Bignell, Ruaidhrà Campion +1
Drawing upon well established zero-temperature techniques, we present, for the first time in a lattice calculation, insight into the fate of the exotic charmonium state at…
Approaching the continuum with anisotropic lattice thermodynamics
Jon-Ivar Skullerud, Gert Aarts, Chris Allton +12
The FASTSUM collaboration has a long-standing programme of using anisotropic lattice QCD to investigate strong interaction thermodynamics, and in particular spectral quantities. He…
