The puzzle of apparent linear lattice artifacts in the 2d non-linear sigma-model and Symanzik's solution
Janos Balog, Ferenc Niedermayer, Peter Weisz
Lattice artifacts in the 2d O(n) non-linear sigma-model are expected to be of the form O(a^2), and hence it was (when first observed) disturbing that some quantities in the O(3) mo…
Logarithmic corrections to O(a^2) lattice artifacts
Janos Balog, Ferenc Niedermayer, Peter Weisz
We compute logarithmic corrections to the O(a^2) lattice artifacts for a class of lattice actions for the non-linear O(n) sigma-model in two dimensions. The generic leading artifac…
Scaling function in AdS/CFT from the O(6) sigma model
Z. Bajnok, J. Balog, B. Basso +2
Asymptotic behavior of the anomalous dimensions of Wilson operators with high spin and twist is governed in planar N=4 SYM theory by the scaling function which coincides at strong…
Bethe--Salpeter wave functions in integrable models
Sinya Aoki, Janos Balog, Peter Weisz
We investigate some properties of Bethe--Salpeter wave functions in integrable models. In particular we illustrate the application of the operator product expansion in determining…
