Taste breaking in the minimally doubled Karsten-Wilczek action and its tree-level improvement
S. Borsányi, S. Capitani, Z. Fodor +4
Minimally doubled fermion actions offer a discretization for two-flavor Quantum Chromodynamics without rooting, but retaining a U(1) chiral symmetry at the same time. The price to…

Taste-splittings of staggered, Karsten-Wilczek and Borici-Creutz fermions under gradient flow in 2D
Stefano Capitani, Stephan Durr
Karsten-Wilczek and Borici-Creutz fermions show a near-degeneracy of the species involved, similar to the species of staggered fermions. Hence in dimensions all…
