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…
Collapse of Coulomb Bound States of Vector Bosons
V. V. Flambaum, H. B. Tran Tan
Charged spin 1 (vector) particles behave very differently from electrons or scalars in a Coulomb field. For an infinitely heavy point-like nucleus their bound state wave functions…
Constraints on the Variation of the QCD Interaction Scale
V. V. Flambaum, A. J. Mansour
Laboratory and astrophysical tests of ''constant variation'' have so far concentrated on the dimensionless fine-structure constant and on the electron or quark mass ratios $X_…
Enhancement of Weak Interactions in Phase Transitions in Condensed Matter and Early Universe
V. V. Flambaum
Parity-violating weak interactions produce extremely small energy differences between left- and right-handed chiral systems. We show that these microscopic effects may be strongly…
