Noncommutative corrections to classical black holes
Archil Kobakhidze
We calculate leading long-distance noncommutative corrections to the classical Schwarzschild black hole which is sourced by a massive noncommutative scalar field. The energy-moment…
Renormalization-scale independence of the physical cosmological constant
Robert Foot, Archil Kobakhidze, Kristian L. McDonald +1
Treating the metric as a classical background field, we show that the cosmological constant does not run with the renormalization scale -- contrary to some claims in the literature…
Aharonov-Bohm interactions of a vector unparticle
Archil Kobakhidze
Recently Georgi argued that hypothetical conformally invariant hidden sector weakly interacting with ordinary particles will have unusual manifestations at low energies in terms of…
SU(5) grand unification on a domain-wall brane from an E_6-invariant action
Aharon Davidson, Damien P. George, Archil Kobakhidze +2
An SU(5) grand unification scheme for effective 3+1-dimensional fields dynamically localised on a domain-wall brane is constructed. This is achieved through the confluence of the c…
A solution to the hierarchy problem from an almost decoupled hidden sector within a classically scale invariant theory
Robert Foot, Archil Kobakhidze, Kristian L. McDonald +1
If scale invariance is a classical symmetry then both the Planck scale and the weak scale should emerge as quantum effects. We show that this can be realized in simple scale invari…
Particle interference as a test of Lorentz-violating electrodynamics
Archil Kobakhidze, Bruce H. J. McKellar
In Lorentz-violating electrodynamics a steady current (and similarly a static charge) generates both static magnetic and electric fields. These induced fields, acting on interferin…
