A new look at the modified Coulomb potential in a strong magnetic field
N. Sadooghi, A. Sodeiri Jalili
The static Coulomb potential of Quantum Electrodynamics (QED) is calculated in the presence of a strong magnetic field in the lowest Landau level (LLL) approximation using two diff…
Axial anomaly of QED in a strong magnetic field and noncommutative anomaly
N. Sadooghi, A. Jafari Salim
The Adler-Bell-Jackiw (ABJ) anomaly of a 3+1 dimensional QED is calculated in the presence of a strong magnetic field. It is shown that in the regime with the lowest Landau level (…
Dynamics of O(N) Model in a Strong Magnetic Background Field as a Modified Noncommutative Field Theory
Amir Jafari Salim, Neda Sadooghi
In the presence of a strong magnetic field, the effective action of a composite scalar field in an scalar O(N) model is derived using two different methods. First, in the framework…
On the Anomalies and Schwinger Terms in Noncommutative Gauge Theories
F. Ardalan, H. Arfaei, N. Sadooghi
Invariant (nonplanar) anomaly of noncommutative QED is reexamined. It is found that just as in ordinary gauge theory UV regularization is needed to discover anomalies, in noncommut…
Planar and Nonplanar Konishi Anomalies and Effective Superpotential for Noncommutative N=1 Supersymmetric U(1)
Farhad Ardalan, Neda Sadooghi
The Konishi anomalies for noncommutative N=1 supersymmetric U(1) gauge theory arising from planar and nonplanar diagrams are calculated. Whereas planar Konishi anomaly is the expec…
