Conceptual design of the International Axion Observatory (IAXO)
The International Axion Observatory (IAXO) will be a forth generation axion helioscope. As its primary physics goal, IAXO will look for axions or axion-like particles (ALPs) originating in the Sun
Black holes, gravitational waves and fundamental physics: a roadmap
The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravity
The International Axion Observatory IAXO. Letter of Intent to the CERN SPS committee
This Letter of Intent describes IAXO, the International Axion Observatory, a proposed 4th generation axion helioscope. As its primary physics goal, IAXO will look for axions or axion-like particles
Dynamical Volume Element in Scale-Invariant and Supergravity Theories ∗
The use in the action integral of a volume element of the form �d D x, whereis a metric-independent measure density, can yield new inter- esting results in all types of known generally
CONFINEMENT EFFECT AS A RESULT OF SPONTANEOUS BREAKING OF SCALE INVARIANCE
In this paper the consequences of introducing spontaneous symmetry breaking of scale invariance through a scale that is obtained from the integration of the equations of motion of four index field
Emergent cosmology, inflation and dark energy
A new class of gravity–matter models defined in terms of two independent non-Riemannian volume forms (alternative generally covariant integration measure densities) on the space–time manifold are
Unified dark energy and dust dark matter dual to quadratic purely kinetic K-essence
We consider a modified gravity plus single scalar-field model, where the scalar Lagrangian couples symmetrically both to the standard Riemannian volume-form (spacetime integration measure density)
A two measure model of dark energy and dark matter
In this work we construct a unified model of dark energy and dark matter. This is done with the following three elements: a gravitating scalar field, with a non-conventional kinetic term, as in the
SPHERICALLY SYMMETRIC AND ROTATING WORMHOLES PRODUCED BY LIGHTLIKE BRANES
Lightlike p-branes (LL-branes) with dynamical (variable) tension allow simple and elegant Polyakov-type and dual to it Nambu–Goto-like worldvolume action formulations. Here we first briefly describe
