On Noncommutative Open String Theories
نویسنده
چکیده
We investigate new compactifications of OM theory giving rise to a 3+1 dimensional open string theory with noncommutative x-x and x-x coordinates. The theory can be directly obtained by starting with a D3 brane with parallel (near critical) electric and magnetic field components, in the presence of a RR scalar field. The magnetic parameter permits to interpolate continuously between the x-x noncommutative open string theory and the x-x spatial noncommutative U(N) super Yang-Mills theory. We discuss SL(2, Z) transformations of this theory. Using the supergravity description of the large N limit, we also compute corrections to the quark-antiquark Coulomb potential arising in the NCOS theory.

Noncommutative Open String Theories and Their Dualities
The recently found non-critical open string theories is reviewed. These open strings, noncommutative open string theories (NCOS), arise as consistent quantum theories describing the low energy theory of D-branes in a background electric B-field in the critical limit. Focusing on the D3-brane case, we construct the most general (3+1) NCOS, which is described by four parameters. We study S and T ...
متن کاملSpace-Time Noncommutative Field Theories And Unitarity
We study the perturbative unitarity of noncommutative scalar field theories. Field theories with space-time noncommutativity do not have a unitary S-matrix. Field theories with only space noncommutativity are perturbatively unitary. This can be understood from string theory, since space noncommutative field theories describe a low energy limit of string theory in a background magnetic field. On...
متن کاملS-Duality from OM-Theory
We study the compactification of OM-theory on tori and show a simple heuristic derivation of the S-duals of noncommutative open string theory in diverse dimensions from the OM-theoretical point of view. In particular, we identify the S-duality between noncommutative open string theory and noncommutative Yang-Mills theory in (3 + 1) dimensions as the exchange of two circles of a torus on which O...
متن کاملUV/IR Mixing in Noncommutative Field Theories and Open Closed String Duality
In this paper we study the phenomenon of UV/IR mixing in noncommutative field theories from the point of view of world-sheet openclosed duality in string theory. New infrared divergences in noncommutative field theories arise as a result of integrating over high momentum modes in the loops. These are believed to come from integrating out additional bulk closed string modes. We analyse this issu...
متن کاملA Note on D - Branes of Odd Codimensions
On a noncommutative space of rank-1, we construct a codimension-one soliton explicitly and, in the context of noncommutative bosonic open string field theory, identify it with the D24-brane. We compute the tension of the proposed D24-brane, yielding an exact value and show that it is related to the tension of the co-dimension two D23-brane by the string T-duality. This resolves a puzzle posed b...
