D-Brane Recoil and Supersymmetry Obstruction
A. Campbell-Smith, N. E. Mavromatos
We discuss a model in which our universe is pictured as a recoiling Dirichlet brane: we find that a proper treatment of the recoil leads naturally to supersymmetry obstruction on t…
D-Brane Recoil and Supersymmetry Breaking as a Relaxation Process
A. Campbell-Smith, N. E. Mavromatos
We propose a new mechanism for the formation of conical singularities on D-branes by means of recoil resulting from scattering of closed string states propagating in the (large) tr…
Light-Cone Broadening and TeV Scale Extra Dimensions
A. Campbell-Smith, John Ellis, N. E. Mavromatos +1
We examine the effect of light-cone broadening induced by quantum-gravity foam in the context of theories with ``large'' extra dimensions stretching between two parallel brane worl…
Gauge Coupling Instability and Dynamical Mass Generation in N=1 Supersymmetric QED(3)
A. Campbell-Smith, N. E. Mavromatos, J. Papavassiliou
Using superfield Dyson-Schwinger equations, we compute the infrared dynamics of the semi-amputated full vertex, corresponding to the effective running gauge coupling, in N-flavour…
On dynamical mass generation in three dimensional supersymmetric U(1) gauge field theory
A. Campbell-Smith, N. E. Mavromatos
We investigate and contrast the non-perturbative infra red structure of N=1 and N=2 supersymmetric non-compact U(1) gauge field theory in three space-time dimensions with N matter…
Composite Operator Effective Potential Approach to QED
A. Campbell-Smith
The composite operator effective potential is compared with the conventional Dyson-Schwinger method as a calculational tool for (2+1)-dimensional quantum electrodynamics. It is fou…
