Domain wall fermions
Thomas Blum, Yigal Shamir
We introduce the formulation of domain wall fermions in the context of lattice QCD. We prove the recovery of exact chiral symmetry in the limit of an infinite fifth direction, and…
Symmetric mass generation and the Nielsen-Ninomiya theorem
Maarten Golterman, Yigal Shamir
The symmetric mass generation (SMG) approach to the construction of lattice chiral gauge theories attempts to use interactions to render mirror fermions massive without symmetry br…
Constraints on the symmetric mass generation paradigm for lattice chiral gauge theories
Maarten Golterman, Yigal Shamir
Within the symmetric mass generation (SMG) approach to the construction of lattice chiral gauge theories, one attempts to use interactions to render mirror fermions massive without…
Power counting of the pion-dilaton effective field theory
Maarten Golterman, Yigal Shamir
Confining QCD-like theories close to the conformal window have a ``walking'' coupling. This is believed to lead to a light singlet scalar meson in the low-energy spectrum, a dilato…
