| Abstract: |
The FASTSUM collaboration has a long-standing project examining hadronic properties usinganisotropic lattice QCD. We determine the spectral properties of bottomonia at finite temperatureusing lattice NRQCD and describe how our newer simulations improve our control over systematicerrors. Motivated by these efforts, the temperature dependence of charm hadron masses isdetermined where it is found that temperature effects can extend into the confining phase and thatsome species remain stable deep past the pseudo-critical temperature. |

Weacknowledge EuroHPC Joint Undertaking for awarding the project EHPC-EXT-2023E01010 access to LUMI-C, Finland. This work used the DiRAC Data Intensive service (DIaL2 & DIaL) at the University of Leicester, managed by the University of Leicester Research Computing Service on behalf of the STFC DiRAC HPC Facility (www.dirac.ac.uk). The DiRAC service at Leicester was funded by BEIS, UKRI and STFC capital funding and STFC operations grants. This work used the DiRAC Extreme Scaling service (Tesseract) at the University of Edinburgh, managed by the Edinburgh Parallel Computing Centre on behalf of the STFC DiRAC HPC Facility (www.dirac.ac.uk). The DiRACservice at Edinburgh was funded byBEIS,UKRIandSTFCcapital funding and STFC operations grants. DiRAC is part of the UKRI Digital Research Infrastructure. This work was performed using the PRACE Marconi-KNLresources hosted by CINECA, Italy.
