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…
Universal BPS structure of stationary supergravity solutions
Guillaume Bossard, Hermann Nicolai, K. S. Stelle
We study asymptotically flat stationary solutions of four-dimensional supergravity theories via the associated G/H* pseudo-Riemannian non-linear sigma models in three spatial dimen…
Gravitational multi-NUT solitons, Komar masses and charges
Guillaume Bossard, Hermann Nicolai, K. S. Stelle
Generalising expressions given by Komar, we give precise definitions of gravitational mass and solitonic NUT charge and we apply these to the description of a class of Minkowski-si…
E10 and Gauged Maximal Supergravity
Eric A. Bergshoeff, Olaf Hohm, Axel Kleinschmidt +3
We compare the dynamics of maximal three-dimensional gauged supergravity in appropriate truncations with the equations of motion that follow from a one-dimensional E10/K(E10) coset…
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…
Effective Action, Conformal Anomaly and the Issue of Quadratic Divergences
Krzysztof A. Meissner, Hermann Nicolai
For massless theory, we explicitly compute the lowest order non-local contributions to the one-loop effective action required for the determination of the trace anomaly. Impo…
