We focus on SYM with a general gauge group G coupled to standard matter in arbitrary represen- tations of G (consistent with a non{positive beta{function). The situation is particularly tricky and interesting when the matter consists of an odd number of half {hypermultiplets: we describe in detail SU(6) SYM coupled to a 1 20, SO(12) SYM coupled to a 1 32, and E7 SYM coupled to a 1 56.Read More
