Signatures of gravity-mediated dark matter interaction in theories with large extra dimensions
A. Clarke, V. V. Flambaum, M. Pospelov +1
Dark matter particles that couple to the Standard Model only through gravity are usually regarded as inaccessible to laboratory detection. This expectation can change in theories w…
Effects of dispersion parity-violating interaction in electron scattering and atoms
V. V. Flambaum, I. B. Samsonov
Exchange of two neutrinos (as well as other fermions) generates a long-range parity-violating potential of the form , with characteristic range . In a…
Oscillations of dark matter halos in galaxies and their effects on motion of stars
V. V. Flambaum, I. B. Samsonov
Matter and dark matter in galaxies represent two main components linked by the gravitational interaction. Collisions of galaxies may create an offset between the centers of mass of…
Analytic action principle in AdS harmonic superspace
Timothy Gargett, Igor Samsonov
We develop the analytic action principle in the AdS harmonic superspace and apply it for studying the component structure of the free -hypermultiplet model.
Massless higher-spin supermultiplets in 5D harmonic superspace
Evgeny I. Buchbinder, Sergei M. Kuzenko, Igor B. Samsonov
Off-shell actions for massless higher-spin supermultiplets in five dimensions (5D) are constructed in harmonic superspace in terms of unconstrained prepotentials. C…
On three-dimensional supersymmetry: maximally supersymmetric backgrounds and massive deformations
Sergei M. Kuzenko, Emmanouil S. N. Raptakis, Igor B. Samsonov +1
Using the superspace formulation for -extended conformal supergravity in three dimensions, we derive all maximally supersymmetric backgrounds in the ${\cal…
