CP violation and gravity as the weakest force
Archil Kobakhidze
We argue that CP violation has rather dramatic impact on the "gravity as the weakest force" conjecture. Namely we find that new ultraviolet scale must be , wher…
(De)quantization of black hole charges
Archil Kobakhidze, Bruce H. J. McKellar
We argue that magnetic and electric charges of the Reissner-Nordstrom black hole are quantized in CP conserving theories. Dequantization phenomenon occurs when CP is broken either…
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…
Ghost Tachyon Condensation, Brane-like States and Extra Time Dimension
Masud Chaichian, Archil Kobakhidze, Dimitry Polyakov
NSR superstring theory contains a tower of physical vertex operators (brane-like states) which exist at non-zero pictures only, i.e. are essentially mixed with superconformal ghost…
Extra dimensions and self-organizing criticality
A. B. Kobakhidze
We discuss a possible explanation of the hierarchy problem within the theories with spacetime dimensions higher than four. We show that the presence of relatively (not hierarchical…
High-dimensional sources for the four-dimensional gravity
M. Chaichian, M. Gogberashvili, A. B. Kobakhidze
We argue that a certain distribution of matter in higher dimensions can provide the correct behaviour of gravity in four dimensions. Some explicit examples illustrating the idea ar…
