On the eta-invariant in the 4D chiral U(1) theory
V. Bornyakov, A. Hoferichter, G. Schierholz +1
In contrast to its counterpart in a vector theory, the effective action of a chiral gauge theory may have a non-vanishing imaginary part. It consists of the so-called Chern-Simons…

Lattice Chiral Schwinger Model: Selected Results
V. Bornyakov, G. Schierholz, A. Thimm
We discuss a method for regularizing chiral gauge theories. The idea is to formulate the gauge fields on the lattice, while the fermion determinant is regularized and computed in t…
