Screening in three-dimensional QED
E. Abdalla, R. Banerjee
We compute the quark-antiquark potential in three dimensional massive Quantum Electrodynamics. The result indicates that screening prevails for large quark masses, contrary to the…
Screening in Two-dimensional QCD
E. Abdalla, R. Mohayaee, A. Zadra
We discuss the issue of screening and confinement of external colour charges in bosonised two-dimensional quantum chromodynamics. Our computation relies on the static solutions of…
Massive Two-Dimensional Quantum Chromodynamics
E. Abdalla, M. C. B. Abdalla, K. D. Rothe
In this work we study the zero-charge sector of massive two-dimensional Quantum Chromodynamics in the decoupled formulation. We find that some general features of the massless theo…
Updating QCD
E. Abdalla, M. C. B. Abdalla
We review two-dimensional QCD. The report contains: 1. Introduction. 2. QCD as a field theory 2.1 The 1/N expansion and spectrum, 2.2 Ambiguity in the self-energy of the quark,…
Higher algebras and mesonic spectrum in two-dimensional QCD
E. Abdalla, M. C. B. Abdalla
We construct composite operators in two-dimensional bosonized QCD, which obey a algebra, and discuss their relation to analogous objects recently obtained in the fermion…
On the amplitudes for non-critical n=2 supuerstrings
E. Abdalla, M. C. B. Abdalla, D. Dalmazi
We compute correlation functions in non critical superstrings on the sphere. Our calculations are restrained to the () bulk amplitudes. We show that the four point funct…
