Query: Charging the Superconformal Index   The superconformal index is an important invariant of superconformal field
theories. In this note we refine the superconformal index by inserting the
charge conjugation operator C. We construct a matrix integral for this charged
index for N=4 SYM with SU(N) gauge group. The key ingredient for the
construction is a "charged character," which reduces to Tr(C) for singlet
representations of the gauge group. For each irreducible real SU(N)
representation, we conjecture that this charged character is equal to the
standard character for a corresponding representation of SO(N+1) or SP(N-1),
for N even or odd respectively. The matrix integral for the charged index
passes tests for small N and for N -> infinity. Like the ordinary
superconformal index, for N=4 SYM the charged index is independent of N in the
large-N limit.
