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…

Quenched QCD near the chiral limit
M. Gockeler, R. Horsley, D. Petters +3
A numerical study of quenched QCD for light quarks is presented using O(a) improved fermions. Particular attention is paid to the possible existence and determination of quenched c…
