Dimensionless Coupling of Superstrings to Supersymmetric Gauge Theories and Scale Invariant Superstring Actions
M. Awada, F. Mansouri
We construct new superstring actions which are distinguished from standard superstrings by being space-time scale invariant. Like standard superstrings, they are also reparametriza…
Supersymmetric Wilson Loops, Superstring-Like Observables, and the Natural Coupling of Superstrings to Supersymmetric Gauge Theories
M. Awada, F. Mansouri
We obtain an explicit expression for the supersymmetric Wilson loop in terms of chiral superfields and supercurrents in superspace. The result turns out to be different from what o…
Renormalizability and Quantum Stability of the Phase Transition in Rigid String Coupled to Kalb-Ramond Fields II
Moustafa Awada
Recently we have shown that a phase transition occurs in the leading approximation of the large N limit in rigid strings coupled to long range Kalb-Ramond interactions. The disorde…

Quantum Stability of the Phase Transition in Rigid QED
M. Awada, D. Zoller, J. F. Clark
Rigid QED is a renormalizable generalization of Feynman's space-time action characterized by the addition of the curvature of the world line (rigidity). We have recently shown that…
Asymptotic Freedom in a String Model of High Temperature QCD
Moustafa Awada
Recently we have shown that a phase transition occurs in the leading and sub-leading approximation of the large N limit in rigid strings coupled to long range Kalb-Ramond interacti…
