T-Duality in Superspace
M. Abou-Zeid, C. M. Hull, U. Lindström +1
We find the T-duality transformation rules for 2-dimensional (2,1) supersymmetric sigma-models in (2,1) superspace. Our results clarify certain aspects of the (2,1) sigma model geo…
Einstein Supergravity and New Twistor String Theories
Mohab Abou-Zeid, Christopher M. Hull, Lionel J. Mason
A family of new twistor string theories is constructed and shown to be free from world-sheet anomalies. The spectra in space-time are calculated and shown to give Einstein supergra…
A Chiral Perturbation Expansion for Gravity
M. Abou-Zeid, C. M. Hull
A formulation of Einstein gravity, analogous to that for gauge theory arising from the Chalmers-Siegel action, leads to a perturbation theory about an asymmetric weak coupling limi…
Comments on the Energy-Momentum Tensor in Non-Commutative Field Theories
Mohab Abou-Zeid, Harald Dorn
In a non-commutative field theory, the energy-momentum tensor obtained from the Noether method needs not be symmetric; in a massless theory, it needs not be traceless either. In a…
Dynamics of Wilson Observables in Non-Commutative Gauge Theory
Mohab Abou-Zeid, Harald Dorn
An equation for the quantum average of the gauge invariant Wilson loop in non-commutative Yang-Mills theory with gauge group U(N) is obtained. In the 't Hooft limit, the equation r…
Actions for Curved Branes
Mohab Abou-Zeid
The nondeterminantal forms of the Born-Infeld and related brane actions in which the gauge fields couple to both an induced metric and an intrinsic metric are generalised by lettin…
