Abstract
For Yang-Mills theories in four dimensions, we propose to rescale the ratio between topologicalsusceptibility and string tension squared in a universal way, dependent only on group factors. We applythis suggestion to SU(Nc ) and Sp(Nc ) groups, and compare lattice measurements performed by severalindependent collaborations. We show that the two sequences of (rescaled) numerical results in these twofamilies of groups are compatible with each other. We hence perform a combined fit, and extrapolate tothe common large-Nc limit.

The work of DV is supported in part by the INFN HPC-HTC project and in part by the Simons Foundation under the program “Targeted Grants to Institutes” awarded to the Hamilton Mathematics Institute. Numerical simulations have been performed on the Swansea University SUNBIRD cluster (part of the Supercomputing Wales project) and AccelerateAI A100 GPU system, on the local HPC clusters in Pusan National University (PNU) and in National Yang Ming Chiao Tung University (NYCU), and the DiRAC Data Intensive service at Leicester. The Swansea University SUNBIRD system and AccelerateAI are part funded by the European Regional Development Fund (ERDF) via Welsh Government. The DiRAC Data Intensive service at Leicester is operated by the University of Leicester IT Services, which forms part of the STFC DiRAC HPC Facility (www.dirac.ac.uk). The DiRAC Data Intensive service equipment at Leicester was funded by BEIS capital funding via STFC capital grants ST/K000373/1 and ST/R002363/1 and STFC DiRAC Operations grant ST/R001014/1. DiRAC is part of the National e-Infrastructure.
