- New developments in the quantization of supersymmetric solitons (kinks, vortices and monopoles) Anton Rebhan Peter van Nieuwenhuizen Robert Wimmer Física, Astronomía y Matemáticas We discuss the one-loop quantum corrections to the mass M and central charge Z of supersymmetric (susy)solitons: the kink, the vortex and the monopole. Contrary to previous expectations and published results, ineach of these cases there are nonvanishing quantum corrections to the mass. For the N = 1 kink and theN = 2 monopole a new anomaly in Z rescues BPS saturation (M = Z); for the N = 2 vortex, BPS saturationis rescued for two reasons: (i) the quantum fluctuations of the Higgs field acquire a nontrivial phase due tothe winding of the classical solution, and (ii) a fermionic zero mode used in the literature is shown not to benormalizable. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434702 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.34
