The rooting issue for a lattice fermion formulation similar to staggered fermions but without taste mixing
David H. Adams
To investigate the viability of the 4th root trick for the staggered fermion determinant in a simpler setting, we consider a two taste (flavor) lattice fermion formulation with no…
Taste symmetry breaking with HYP-smeared staggered fermions
Taegil Bae, David H. Adams, Chulwoo Jung +5
We study the impact of hypercubic (HYP) smearing on the size of taste breaking for staggered fermions, comparing to unimproved and to asqtad-improved staggered fermions. As in prev…
Improvement of the pion spectrum with HYP-smeared staggered fermions
Taegil Bae, David Adams, Chulwoo Jung +5
We extend our previous study of taste-symmetry breaking using HYP-smeared staggered fermions in two ways. First, we improve the statistics of a comparison of unimproved and HYP-sme…
Structure of logarithmically divergent one-loop lattice Feynman integrals
David H. Adams, Weonjong Lee
For logarithmically divergent one-loop lattice Feynman integrals I(p,a), subject to mild general conditions, we prove the following expected and crucial structural result: I(p,a) =…
Renormalisation group evolution for the effective Hamiltonian with
David H. Adams, Weonjong Lee
We discuss the renormalisation group (RG) evolution for the operators in unquenched QCD with () or, more generally, ()…
Dirac operator index and topology of lattice gauge fields
David H. Adams
The fermionic topological charge of lattice gauge fields, given in terms of a spectral flow of the Hermitian Wilson--Dirac operator, or equivalently, as the index of Neuberger's la…
