CP-violating decays of the pseudoscalars eta and eta' and their connection to the electric dipole moment of the neutron
Thomas Gutsche, Astrid N. Hiller Blin, Sergey Kovalenko +4
Using the present upper bound on the neutron electric dipole moment, we give an estimate for the upper limit of the CP-violating couplings of the eta(eta') to the nucleon. Using th…
Symmetries in superintegrable deformations of oscillator/Coulomb systems: "holomorphic factorization"
Tigran Hakobyan, Armen Nersessian, Hovhannes Shmavonyan
We propose a unified description for the constants of motion for superintegrable deformations of the oscillator and Coulomb systems on N-dimensional Euclidean space, sphere and hyp…
One-loop divergences in 6D, N=(1,0) SYM theory
I. L. Buchbinder, E. A. Ivanov, B. S. Merzlikin +1
We consider, in the harmonic superspace approach, the six-dimensional N=(1,0) supersymmetric Yang-Mills gauge multiplet minimally coupled to a hypermultiplet in an arbitrary repres…
Eisenhart lift for higher derivative systems
Anton Galajinsky, Ivan Masterov
The Eisenhart lift provides an elegant geometric description of a dynamical system of second order in terms of null geodesics of the Brinkmann-type metric. In this work, we attempt…
Reduction of friction by normal oscillations. I. Influence of contact stiffness
Mikhail Popov, Valentin L. Popov, Nikita V. Popov
The present paper is devoted to a theoretical analysis of sliding friction under the influence of oscillations perpendicular to the sliding plane. In contrast to previous works we…
Discreteness of Point Charge in Nonlinear Electrodynamics
A. I. Breev, A. E. Shabad
We consider two point charges in electrostatic interaction between them within the framework of a nonlinear model, associated with QED, that provides finiteness of their field ener…
