On Continuous Moyal Product Structure in String Field Theory
نویسنده
چکیده
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. ∗On leave from Steklov Mathematical Institute, Moscow, Russia.

String Star as a Continuous Moyal Product
We establish that the open string star product in the zero momentum sector can be described as a continuous tensor product of mutually commuting two dimensional Moyal star products. Let the continuous variable κ ∈ [ 0,∞) parametrize the eigenvalues of the Neumann matrices; then the noncommutativity parameter is given by θ(κ) = 2 tanh( 4 ). For each κ, the Moyal coordinates are a linear combinat...

متن کاملMoyal Formulation of Witten’s Star Product in the Fermionic Ghost Sector
In this paper, we recast the fermionic ghost sector of Witten’s open bosonic string field theory in the language of noncommutative field theory. In particular, following the methods of hep-th/0202087, we find that in Siegel gauge Witten’s star product roughly corresponds to a continuous tensor product of Clifford Algebras, and we formulate important operators of the theory in this language, not...
متن کاملUT - 03 - 08 April , 2003 Fermionic Ghosts in Moyal String Field Theory
We complete the construction of the Moyal star formulation of bosonic open string field theory (MSFT) by providing a detailed study of the fermionic ghost sector. In particular, as in the case of the matter sector, (1) we construct a map from Witten's star product to the Moyal product, (2) we propose a regularization scheme which is consistent with the matter sector and (3) as a check of the fo...
