On Continuous Moyal Product Structure in String Field Theory
arXiv:hep-th/0207174 · doi:10.1088/1126-6708/2002/10/049
Abstract
We consider a diagonalization of Witten's star product for a ghost system of arbitrary background charge and Grassmann parity. To this end we use a bosonized formulation of such systems and a spectral analysis of Neumann matrices. We further identify a continuous Moyal product structure for a combined ghosts+matter system. The normalization of multiplication kernel is discussed.
