Conformal invariance from non-conformal gravity
Krzysztof A. Meissner, Hermann Nicolai
We discuss the conditions under which classically conformally invariant models in four dimensions can arise out of non-conformal (Einstein) gravity. As an `existence proof' that th…
Horizons and the cosmological constant
Krzysztof A. Meissner
A new solution of the Einstein equations for the point mass immersed in the de Sitter Universe is presented. The properties of the metric are very different from both the Schwarzsc…
Neutrinos, Axions and Conformal Symmetry
Krzysztof A. Meissner, Hermann Nicolai
We demonstrate that radiative breaking of conformal symmetry (and simultaneously electroweak symmetry) in the Standard Model with right-chiral neutrinos and a minimally enlarged sc…
First results from the OSQAR photon regeneration experiment: No light shining through a wall
OSQAR Collaboration, Pierre Pugnat, Lionel Duvillaret +13
A new method to amplify the photon-axion conversions in magnetic field is proposed using a buffer gas at a specific pressure. As a first result, new bounds for mass and coupling co…
