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 $…

Finite temperature hadronic spectral properties

Ryan Bignell, Gert Aarts, Chris Allton +9

The FASTSUM collaboration has a long-standing project examining hadronic properties using anisotropic lattice QCD. We determine the spectral properties of bottomonia at finite temp…

Spectral properties of bottomonium at high temperature: a systematic investigation

Jon-Ivar Skullerud, Gert Aarts, Chris Allton +11

We investigate spectral features of bottomonium at high temperature, in particular the thermal mass shift and width of ground state S-wave and P-wave state. We employ and compare a…

Anisotropic excited bottomonia from a basis of smeared operators

Ryan Bignell, Gert Aarts, Chris Allton +9

Bottomonia play a crucial role in our understanding of the quark gluon plasma. We present lattice non-relativistic QCD calculations of bottomonia at temperatures in the range $T \i…

The NRQCD spectrum at non-zero temperature using Backus-Gilbert regularisations

Antonio Smecca, Gert Aarts, Chris Allton +10

Understanding how the properties of heavy mesons change as temperature increases is crucial for gaining valuable insights into the quark-gluon plasma. Information about meson masse…

Thermal lattice QCD results from the FASTSUM collaboration

Chris Allton, Gert Aarts, M. Naeem Anwar +12

The FASTSUM Collaboration has developed a comprehensive research programme in thermal lattice QCD using 2+1 flavour ensembles. We review our recent hadron spectrum analyses of open…
