Geometrical formalism in gauge theories
Yuri A. Kubyshin
We review the basic elements of the geometrical formalism for description of gauge fields and the theory of invariant connections, and their applications to the coset space dimensi…
Time variation of the gravitational and fine structure constants in models with extra dimensions
E. Garcia-Berro, Yu. A. Kubyshin, P. Loren-Aguilar
We derive formulae for the time variation of the gravitational ``constant'' and of the fine structure ``constant'' in various models with extra dimensions and analyze their consist…
Models with Extra Dimensions and Their Phenomenology
Yuri A. Kubyshin
The Arkani-Hamed-Dimopoulos-Dvali and the Randall-Sundrum models with extra spacelike dimensions, recently proposed as a solution to the hierarchy problem, are reviewed. We discuss…
Effective Lagrangians for linearized gravity in Randall-Sundrum model
Edward E. Boos, Yuri A. Kubyshin, Mikhail N. Smolyakov +1
We construct the second variation Lagrangian for Randall-Sundrum model with two branes, study its gauge invariance, find the corresponding equations of motion and decouple them. We…
Gauge invariant regularisation in the ERG approach
S. Arnone, Yu. A. Kubyshin, T. R. Morris +1
A gauge invariant regularisation which can be used for non-perturbative treatment of Yang-Mills theories within the exact renormalization group approach is constructed. It consists…
Instanton propagator in scalar model: exact expression and contribution to instanton induced processes
Yu. A. Kubyshin, P. G. Tinyakov
The propagator in the instanton background in the -lambda phi^4 scalar model in four dimensions is studied. Leading and sub-leading terms of its asymptotics for large momenta and i…
