Physics at Underground Laboratories: Direct Detection of Dark Matter
- Physics
- 2009
Underground laboratories host two kind of experiments at the frontier of our knowledge in Particle Physics, Astrophysics and Cosmology: the direct detection of the Dark Matter of the Universe and the…
Inclusive Constraints on Unified Dark Matter Models from Future Large-Scale Surveys
- Physics
- 2012
In the very last years, cosmological models where the properties of the dark components of the Universe — dark matter and dark energy — are accounted for by a single ``dark fluid'' have drawn…
High-energy astrophysics with neutrino telescopes
- Physics
- 2009
Neutrino astrophysics offers new perspectives on the Universe investigation: high-energy neutrinos, produced by the most energetic phenomena in our Galaxy and in the Universe, carry complementary (if…
Vacuum pressure, dark energy and dark matter
- Physics
- 2009
It has been argued that the correct, i.e. positive, sign of quantum vacuum energy density, or more properly, negative sign of quantum vacuum pressure, requires not a very large number, e.g. ~100, of…
An updated analysis of two classes of f(R) theories of gravity
- Physics
- 2012
The observed accelerated cosmic expansion can be a signature of fourth-order gravity theories, where the acceleration of the Universe is a consequence of departures from Einstein General Relativity,…

Fundamental Particle and a New Approach to the Expansion of the Universe
- Physics
- 2013
In this study, the existence of a new subatomic particle called “fundamental particle” and the structure of primary formation matter remnants like dark matter, dark energy etc. are associated with…
The AMS-02 experiment on the ISS
- Physics
- 2009
The Alpha Magnetic Spectrometer (AMS-02) on the International Space Station (ISS) is a large acceptance magnetic spectrometer aiming for high precision studies of cosmic rays in space. The experiment…
Relativistic MOND from modified energetics
- Physics
- 2014
We begin to investigate the question of what modifications in the energy-momentum tensor can yield the correct MOND regime. As a starting study, we refrain from insisting on an action principle and…
Building instructions for a ferromagnetic axion haloscope
- PhysicsThe European Physical Journal Plus
- 2022
A ferromagnetic haloscope is a rf spin-magnetometer used for searching Dark Matter in the form of axions. A magnetic material is monitored searching for anomalous magnetization oscillations which can…

Direct detection of neutralino dark matter in supergravity
- Physics
- 2005
The direct detection of neutralino dark matter is analysed in general supergravity scenarios, where non-universal soft scalar and gaugino masses can be present. In particular, the theoretical…
Indirect detection of dark matter in km size neutrino telescopes
- Physics
- 1998
Neutrino telescopes of kilometer size are currently being planned. They will be two or three orders of magnitude bigger than presently operating detectors, but they will have a much higher muon…
Indirect signals from light neutralinos in supersymmetric models without gaugino mass unification
- Physics
- 2004
We examine indirect signals produced by neutralino self–annihilations, in the galactic halo or inside celestial bodies, in the frame of an effective MSSM model without gaugino-mass unification at a…
Cosmic ray positron excess and neutralino dark matter
- Physics
- 2002
Using a new instrument, the HEAT collaboration has confirmed the excess of cosmic ray positrons that they first detected in 1994. We explore the possibility that this excess is due to the…
Antiproton fluxes from light neutralinos
- Physics
- 2005
We analyze how the measurements of the low-energy spectrum of cosmic antiprotons can provide information on relic neutralinos. The analysis is focused on the light neutralinos which emerge in…
Do current WIMP direct measurements constrain light relic neutralinos
- Physics
- 2005
New upper bounds on direct detection rates have been presented recently by a number of experimental collaborations working on searches for weakly interacting massive particles (WIMPs). In this paper…
Neutralino annihilation into gamma-rays in the Milky Way and in external galaxies
- Physics
- 2004
We discuss the gamma-ray signal from dark matter annihilation in our Galaxy and in external objects, namely, the Large Magellanic Cloud, the Andromeda Galaxy (M31), and M87. We derive predictions for…
Supersymmetric dark matter and the extragalactic gamma ray background.
- PhysicsPhysical review letters
- 2005
We trace the origin of the newly determined extragalactic gamma-ray background from EGRET data to an unresolved population of blazars and neutralino annihilation in cold dark matter halos. Using…
Challenges in detecting gamma-rays from dark matter annihilations in the galactic center
- Physics

Atmospheric Cerenkov Telescopes, including HESS and MAGIC, have detected a spectrum of gamma-rays from the galactic center region which extends from {approx}200 GeV or lower, to at least {approx}10…
Antiprotons in cosmic rays from neutralino annihilation
- Physics

We calculate the antiproton flux due to relic neutralino annihilations, in a two–dimensional diffusion model compatible with stable and radioactive cosmic ray nuclei. We find that the uncertainty in…
