Gauge Invariant Cutoff QED
F. Ardalan, H. Arfaei, M. Ghasemkhani +1
A hidden generalized gauge symmetry of a cutoff QED is used to show the renormalizability of QED. In particular, it is shown that corresponding Ward identities are valid all along…
Double-Horizon Limit and Decoupling of the Dynamics at the Horizon
H. Arfaei, R. Fareghbal
We show that the attractor mechanism for generic black hole is a consequence of the double-horizon. Investigation of equations of motion shows that in the case of the double-horizo…
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…
Gravity on Noncommutative D-Branes
F. Ardalan, H. Arfaei, M. R. Garousi +1
The effective action for the low energy scattering of two gravitons with a D-brane in the presence of a constant antisytmetric field in bosonic string theory is calculated and…
Phenomenological Consequences of Non-commutative QED
H. Arfaei, M. H. Yavartanoo
In the context of the noncommutative QED we consider few phenomena which reflect the noncommutativity. In all of them the new interactions in the Feynmann diagrams that are respons…
Modular Invariant Partition Functions and Method of Shift Vector
H. Arfaei, A. Shirzad
Using shift vector method we obtain a large class of self-dual lattices of dimension , which has a one to one correspondence with modular invariants of free bosonic theory c…
