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…
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…
Inclusive semileptonic decays of the meson: Lattice QCD confronts experiments
Alessandro De Santis, Antonio Evangelista, Roberto Frezzotti +13
We present the results of a first-principles theoretical study of the inclusive semileptonic decays of the meson. We performed a state-of-the-art lattice QCD calculation by…

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…
NRQCD Bottomonium at non-zero temperature using time-derivative moments
Rachel Horohan D'arcy, Gert Aarts, Chris Allton +8
A well-known challenge for the lattice community is calculating the spectral function from the Euclidean correlator. We have approximated the spectral function and derived the mass…
Heavy-light meson decay constants and hyperfine splittings with the heavy-HISQ method
Kerr A. Miller, Judd Harrison, Christine T. H. Davies +1
We compute ratios between the vector and pseudoscalar, and tensor and vector decay constants, and between hyperfine splittings for and mesons. We us…
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…
On the equation of state of U(1) lattice gauge theory in three dimensions
Michele Caselle, Alessandro Mariani, Marco Panero +1
We study the equation of state of three-dimensional compact U(1) gauge theory on the lattice by means of numerical simulations, and discuss the implications of our results for the…
