Abstract

We derive formulas for the characters of the N = 4 algebra A γ which contains two SU(2) Kac-Moody subalgebras. We present results for unitary, highest weight, massive representations in the Ramond and Neveu-Schwarz sectors. Massive characters are given for the A ̃ γ algebra, which is closely related to A γ, with no dimension- 1 2 operators but rather composite operators in the OPE's. Comparison with previously known results in relevant limits are performed.
