Quantum version of the N = 8 superconformal algebra
Abstract
The quantized form of the soft N = 8 superconformal algebra is investigated. Its operator product expansions are shown to exhibit a oneparameterclass of (soft) anomalies, which may be arbitrarily shifted by certain suitable quantum corrections of the generators. In particular, the BRST operator can be constructed and made nilpotent in the quantum version of all known realizations of the algebra. This generalizes the results of Cederwall and Preitschopf, who studied the Ŝ^{7} part that is contained as a soft affine subalgebra in the superconformal algebra. A Fockspace representation is given that is forced to be somewhat unusual in certain modes.
