On non-commutative open string theories
We investigate new compactifications of OM theory giving rise to a (3 + 1)-dimensional open string theory with non-commutative x0-x1 and x2-x3 coordinates. The theory can be directly obtained by starting with a D3-brane with parallel (near critical) electric and magnetic field components, in the pre...

| Sumario: | We investigate new compactifications of OM theory giving rise to a (3 + 1)-dimensional open string theory with non-commutative x0-x1 and x2-x3 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 x0-x1 non-commutative open string theory and the x2-x3 spatial non-commutative 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. |
