Topological susceptibility from twisted mass fermions using spectral projectors and the gradient flow

HIGHLIGHTS

• who: Constantia Alexandrou and collaborators from the DepartmentUniversity of , Frankfurt am Main, Germany have published the Article: Topological susceptibility from twisted mass fermions using spectral projectors and the gradient flow, in the Journal: (JOURNAL) of 28/09/2017
• what: The authors compare lattice QCD determinations of topological susceptibility using a gluonic definition from the gradient flow and a fermionic definition from the spectral-projector method. The authors show that there exists in principle a value of the spectral cutoff which would completely eliminate discretization effects in the topological susceptibility.
• how: While slightly larger . . .
