Chiral fermions from lattice boundaries
Abstract We construct a model in which four-dimensional chiral fermions arise on the boundaries of a five-dimensional lattice with free boundary conditions in the fifth direction. The physicalExpand

Axial symmetries in lattice QCD with Kaplan fermions
Abstract A lattice definition of QCD based on chiral defect fermions is discussed in detail. This formulation involves (infinitely) many heavy regulator fields, realized through the introduction ofExpand

Low-energy effective action for pions and a dilatonic meson
Numerical simulations of QCD-like theories in which the number of flavors is adjusted so that the beta function is very small, but confinement and chiral symmetry breaking nevertheless take place,Expand

Unilateral Neglect in Children with Hemiplegic Cerebral Palsy
The purpose of this study was to examine the pattern of attentional deficits in children with right and left hemiplegic cerebral palsy. Unilateral neglect and visuospatial deficits are commonExpand

Spectroscopy of SU(4) composite Higgs theory with two distinct fermion representations
We have simulated the SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously. Such theories arise naturally inExpand

Effective field theories for QCD with rooted staggered fermions
Even highly improved variants of lattice QCD with staggered fermions show significant violations of taste symmetry at currently accessible lattice spacings. In addition, the 'rooting trick' is usedExpand

Nonperturbative beta function in three-dimensional electrodynamics
We apply the Schr\"odinger functional method to the Abelian gauge theory in three dimensions with ${N}_{f}=2$ four-component fermions. We find that the calculated beta function does not cross zero inExpand

Comment on: “Chiral anomalies and rooted staggered fermions” [Phys. Lett. B 649 (2007) 230]
In hep-lat/0701018, Creutz claims that the rooting trick used in simulations of staggered fermions to reduce the number of tastes misses key physics whenever the desired theory has an odd number ofExpand

Renormalization-group analysis of the validity of staggered-fermion QCD with the fourth-root recipe
I develop a renormalization-group blocking framework for lattice QCD with staggered fermions. Under plausible, and testable assumptions, I then argue that the fourth-root recipe used in numericalExpand

Role of the double pole in lattice QCD with mixed actions
We investigate effects resulting from the use of different discretizations for the valence and the sea quarks in lattice QCD, considering Wilson and/or Ginsparg-Wilson fermions. We assume that suchExpand
