Monopole and dyon spectra in N=2 SYM with higher rank gauge groups

Martin Cederwall (Institutionen för teoretisk fysik och mekanik, Matematisk fysik) ; Magnus Holm (Institutionen för teoretisk fysik)

We derive parts of the monopole and dyon spectra for N=2 super-Yang-Mills theories in four dimensions with gauge groups G of rank r>1 and matter multiplets. Special emphasis is put on G=SU(3) and those matter contents that yield perturbatively finite theories. There is no direct interpretation of the soliton spectra in terms of naive selfduality under strong-weak coupling and exchange of electric and magnetic charges. We argue that, in general, the standard procedure of finding the dyon spectrum will not give results that support a conventional selfduality hypothesis - the SU(2) theory with four fundamental hypermultiplets seems to be an exception. Possible interpretations of the results are discussed.
