Gribov horizon in Noncommutative QED

چکیده
It is known that Noncommutative QED (NCQED) exhibits Gribov ambiguities in the Landau gauge. These are related to zero modes of Faddeev-Popov operator and arise ghost propagator when it has a pole. In this work, we establish positive for NCQED condition not have poles, so-called no-pole condition. This implemented path integral allows calculation photon momentum space, which dependent on squared non-commutativity parameter. commutative limit, standard recovered.

Noncommutative Dipole QED
The noncommutative dipole QED is studied in detail for the matter fields in the adjoint representation. The axial anomaly of this theory is calculated in two and four dimensions using various regularization methods. The Ward-Takahashi identity is proved by making use of a non-perturbative path integral method. The one-loop β-function of the theory is calculated explicitly. It turns out that the...
متن کاملLandau gauge within the Gribov horizon.
We consider a model which effectively restricts the functional integral of Yang–Mills theories to the fundamental modular region. Using algebraic arguments, we prove that this theory has the same divergences as ordinary Yang Mills theory in the Landau gauge and that it is unitary. The restriction of the functional integral is interpreted as a kind of spontaneous breakdown of the BRS symmetry.
متن کاملStrong Field, Noncommutative QED
We review the effects of strong background fields in noncommutative QED. Beginning with the noncommutative Maxwell and Dirac equations, we describe how combined noncommutative and strong field effects modify the propagation of fermions and photons. We extend these studies beyond the case of constant backgrounds by giving a new and revealing interpretation of the photon dispersion relation. Cons...
متن کاملNoncommutative QED and γγ scattering
We study γγ scattering in noncommutative QED (NCQED) where the gauge field has Yang-Mills type coupling, giving new contributions to the scattering process and making it possible for it to occur at tree level. The process takes place at one loop level in the Standard Model (SM) and could be an important signal for physics beyond SM. But it is found that the Standard Model contribution far excee...
متن کاملNoncommutative renormalization for massless QED
We study the renormalization of massless QED from the point of view of the Hopf algebra discovered by D. Kreimer. For QED, we describe a Hopf algebra of renormalization which is neither commutative nor cocommutative. We obtain explicit renormalization formulas for the electron and photon propagators, for the vacuum polarization and the electron self-energy, which are equivalent to Zimmermann’s ...
