Minimally doubled fermions at one-loop level

Understand

Single fermionic degrees of freedom together with standard chiral symmetry at finite lattice spacing, correct continuum limit and local interactions only are precluded by the Nielsen-Ninomiya no-go theorem.

• The class of minimally doubled fermion actions exhibits exactly two chiral modes.
• Recent interest in these actions has been sparked by the investigation of fermionic actions defined on "hyperdiamond" lattices.
• Due to the necessity of breaking hypercubic symmetry explicitly, radiative corrections generate operator mixings with relevant and marginal operators that should vanish in continuum QCD.
