String Amplitudes from Moyal String Field Theory
I. Bars, I. Kishimoto, Y. Matsuo
We illustrate a basic framework for analytic computations of Feynman graphs using the Moyal star formulation of string field theory. We present efficient methods of computation bas…
MSFT : Moyal Star Formulation of String Field Theory
Itzhak Bars
The Moyal star formulation of string field theory is reviewed. The various versions of the star product are compared and related to one another in a regulated theory that resolves…
Hidden 12-dimensional structures in AdS(5)xS(5) and M(4)xR(6) Supergravities
Itzhak Bars
It is shown that AdS(5)xS(5) supergravity has hitherto unnoticed supersymmetric properties that are related to a hidden 12-dimensional structure. The totality of the AdS(5)xS(5) su…
A Mysterious Zero in AdS(5) x S(5) Supergravity
Itzhak Bars
It is shown that all the states in AdS(5) x S(5) supergravity have zero eigenvalue for the all Casimir operators of its symmetry group SU(2,2|4). To compute this universal zero in…
Computing in String Field Theory Using the Moyal Star Product
Itzhak Bars, Yutaka Matsuo
Using the Moyal star product, we define open bosonic string field theory carefully, with a cutoff, for any number of string oscillators and any oscillator frequencies. Through deta…
Associativity Anomaly in String Field Theory
Itzhak Bars, Yutaka Matsuo
We give a detailed study of the associativity anomaly in open string field theory from the viewpoint of the split string and Moyal formalisms. The origin of the anomaly is reduced…
