One-loop surface tensions of (supersymmetric) kink domain walls from dimensional regularization
arXiv:hep-th/0203137 · doi:10.1088/1367-2630/4/1/331
Abstract
We consider domain walls obtained by embedding the 1+1-dimensional -kink in higher dimensions. We show that a suitably adapted dimensional regularization method avoids the intricacies found in other regularization schemes in both supersymmetric and non-supersymmetric theories. This method allows us to calculate the one-loop quantum mass of kinks and surface tensions of kink domain walls in a very simple manner, yielding a compact d-dimensional formula which reproduces many of the previous results in the literature. Among the new results is the nontrivial one-loop correction to the surface tension of a 2+1 dimensional N=1 supersymmetric kink domain wall with chiral domain-wall fermions.
