A specific lattice artefact in non-perturbative renormalization of operators
Vidushi Maillart, Ferenc Niedermayer
We discuss a specific cut-off effect which appears in applying the non-perturbative RI/MOM scheme to compute the renormalization constants. To illustrate the problem a Dirac operat…

Asymptotic freedom with discrete spin variables?
Peter Hasenfratz, Ferenc Niedermayer
We study the critical behaviour of the 2d dodecahedron spin model and investigate the conjecture that the discrete model describes the same continuum theory as the O(3) non-linear…
