Relations between supersymmetric structures in UV and IR for N=4 bad theories

We investigate options for the structure of the infrared fixed points of N = 4 bad theories in three dimensions. Unitarity constraints allow a number of possibilities, not necessarily a product of an interacting N = 4 SCFT and free theories. For each option we provide relations between the UV and IR R symmetry groups. For some of them we give examples. In particular, the N = 4 SU(2) SYM with two fundamental hypermultiplets is an example of a bad theory which flows to an interacting irreducible SCFT in the IR. The question of whether all the options are realized remains open.
