Walking near a conformal fixed point
We investigate the 2-d O(3) model with a q-term as a toy model for slowly walking 4-d nonAbelian gauge theories. Using the very efficient meron-cluster algorithm, an accurate investigation of the scale dependence of the renormalized coupling is carried out for different values of the vacuum angle q....
