Lorentz Violation of Quantum Gravity
J. W. Moffat
A quantum gravity theory which becomes renormalizable at short distances due to a spontaneous symmetry breaking of Lorentz invariance and diffeomorphism invariance is studied. A br…
Noncommutative and Non-Anticommutative Quantum Field Theory
J. W. Moffat
A noncommutative and non-anticommutative quantum field theory is formulated in a superspace, in which the superspace coordinates satisfy noncommutative and non-anticommutative rela…
Perturbative Noncommutative Quantum Gravity
J. W. Moffat
We study perturbative noncommutative quantum gravity by expanding the gravitational field about a fixed classical background. A calculation of the one loop gravitational self-energ…
Noncommutative Quantum Gravity
J. W. Moffat
The possible role of gravity in a noncommutative geometry is investigated. Due to the Moyal *-product of fields in noncommutative geometry, it is necessary to complexify the metric…
Abelian Anomalies in Nonlocal Regularization
M. A. Clayton, L. Demopoulos, J. W. Moffat
Nonlocal regularization of QED is shown to possess an axial anomaly of the same form as other regularization schemes. The Noether current is explicitly constructed and the symmetri…
