The Strong- Problem and its Gauge Axion solution as Evidence for Fundamental Strings
Gia Dvali, Lucy Komisel, Otari Sakhelashvili +1
The topological susceptibility of the QCD vacuum provides an understanding of -vacua as vacua of a Chern-Simons gauge theory. In this way, it gives an immediate proof of the phy…
-meson from topological properties of the electroweak vacuum
Gia Dvali, Archil Kobakhidze, Otari Sakhelashvili
We further scrutinize the evidence for a recently suggested pseudo-scalar particle, the electroweak -meson. Its existence is demanded by matching the removal of the weak…
Similarities in the evaporation of saturated solitons and black holes
Giacomo Contri, Gia Dvali, Otari Sakhelashvili
It has been suggested some time ago that many black hole properties are not specific to gravity, but rather are shared by a large class of objects, the so-called saturons, that sat…
TeV Window to Grand Unification: Higgs's Light Color Triplet Partner
Gia Dvali, Otari Sakhelashvili, Anja Stuhlfauth
The color-triplet partner of the Higgs doublet, called a -particle, is a universal feature of Grand Unification. It has been shown some time ago that this particle can be access…
Coherent States in Gauge Theories: Topological Defects and Other Classical Configurations
Lasha Berezhiani, Gia Dvali, Otari Sakhelashvili
We present a formulation of coherent states as of consistent quantum description of classical configurations in the BRST-invariant quantization of electrodynamics. The quantization…
