Superheavy dark matter and supersymmetry

We discuss supersymmetric Q-balls as possible candidates for dark matter particles, their interaction in matter and astrophysical constraints on their existence. © 2005 Elsevier B.V. All rights reserved. ...

Supersymmetric dark matter Q-balls and their interactions in matter

Supersymmetric extensions of the Standard Model contain nontopological solitons, Q-balls, which can be stable and can be a form of cosmological dark matter. Understanding the interaction of SUSY Q-balls with matter fermions is important for both astrophysi ...

The nuMSM, dark matter and baryon asymmetry of the universe

We show that the extension of the standard model by three right-handed neutrinos with masses smaller than the electroweak scale (the νMSM) can explain simultaneously dark matter and baryon asymmetry of the universe and be consistent with the experiments on ...

Astrophysical bounds on supersymmetric dark-matter Q- balls

Stable baryonic Q-balls, which appear in supersymmetric extensions of the Standard Model, could form at the end of cosmological inflation from fragmentation of the Affleck-Dine condensate. We reconsider astrophysical constraints on such Q-balls as dark mat ...

The nuMSM, dark matter and neutrino masses

Steve Blanchet

We investigate an extension of the Minimal Standard Model by right-handed neutrinos (the νMSM) to incorporate neutrino masses consistent with oscillation experiments. Within this theory, the only candidates for dark matter particles are sterile right-hande ...

Gravitational quantum corrections in warped supersymmetric brane worlds

Riccardo Rattazzi, Claudio Scrucca

We study gravitational quantum corrections in supersymmetric theories with warped extra dimensions. We develop for this a superfield formalism for linearized gauged supergravity. We show that the 1-loop effective Kahler potential is a simple functional of ...

UV metal semiconductor metal detectors - A robust choice for (Al, Ga)N based detectors

Nicolas Grandjean, Mauro Mosca

UV detection is interesting for combustion optimization, air contamination control, fire and solar blind rocket launching detection. Most of these applications require that UV detectors have a huge dynamic response between UV and the visible, and a very lo ...

Primordial constraint on the spatial dependence of the Newton constant

Pierre Vandergheynst, Yves Wiaux

A Nordtvedt effect at cosmological scales affects the acoustic oscillations imprinted in the cosmic microwave background. The gravitational baryonic mass density of the universe is inferred at the first peak scale from WMAP data. The independent determinat ...

Cosmic microwave background constraints on the strong equivalence principle

Pierre Vandergheynst, Yves Wiaux

We study the effect of a violation of the strong equivalence principle (SEP) on the cosmic microwave background (CMB). Such a violation would modify the weight of baryons in the primordial gravitational potentials and hence their impact in the establishmen ...

The new TAE - Alfvén Wave Active Excitation System at JET

Ambrogio Fasoli, Laurent Villard, Duccio Testa, René Chavan, Robert Bertizzolo

After many years of successful operation, the JET saddle coil system will be dismantled during the 2004-2005 shutdown. A new antenna system has been designed and is being constructed to replace it and excite magneto-hydrodynamics modes in the Alfvén freque ...
