The ANTARES observatory is currently the largest neutrino telescope in the Northern Hemisphere. It is well suited to detect high energy neutrinos produced in astrophysical sources as it can observe a full hemisphere of the sky at all the times with a duty cycle close to unity and an angular resolution about 0.3 degrees. Due to its location in the South of France, ANTARES is sensitive to...

KM3NeT ($km^3$ Neutrino Telescope) will be one of the world’s largest particle detectors, built at the bottom of the Mediterranean Sea, providing a window for the observation of the Universe through high energy neutrinos. KM3NeT will complement the South Polar IceCube neutrino telescope in its field of view and significantly surpass it in sensitivity and discovery potential. The underwater...

The determination of neutrino flavor transition mechanism by
neutrino telescopes is presented. We first propose a model-independent parameterization for flavor transitions (such as standard three-flavor oscillations, neutrino decays or others)of astrophysical neutrinos propagating from their sources to the Earth. We demonstrate how one can constrain parameters
of the above parameterization...

We discuss experimental signatures of non-minimal Kaluza-Klein dark matter. In the minimal Universal Extra Dimensions model, there is a unique possible dark matter candidate, the first Kaluza-Klein excitation of the U(1) gauge boson B. On the other hand, in non-minimal models, allowing for general boundary localized terms, the mass spectrum is different, and such models allow for other dark...

The Pierre Auger Observatory is measuring the ultra-high energy cosmic ray extended air showers from simultaneous observation of fluorescence and surface detectors with unprecedented precision. The high statistics of the surface detector allows a good determination of the cosmic ray flux above an energy of 3 EeV. This bound is extended down to 1 EeV...

We report on the analysis of the distribution of the arrival directions of ultra high energy cosmic rays detected at the Pierre Auger Observatory. From $2.10^{17}~$eV to $3.10^{19}~$eV, we present the results of searches for first harmonic modulations in the right-ascension distribution of cosmic rays and discuss the obtained upper limits which constitute the most stringent bounds at present...

The mass composition of ultra-high energy cosmic rays is a critical issue to understand their origin and nature. The Pierre Auger Observatory is a hybrid instrument which
provides a powerful environment for the determination of the primary mass, being able to discriminate between photons, neutrinos and hadrons. Results on limits of photon

The ARGO-YBJ detector, located 4300 m a.s.l. on the Tibet plateau, is a ground-based, full-coverage array of Resistive Plate Chambers (RPCs) covering a surface of 78 x 74 m^2, surrounded by a guard ring of RPCs enclosing a total surface of about 11000 m^2. ARGOYBJ was designed to detect extensive air showers generated by cosmic rays and gamma rays with primary energy greater than few hundred...

The LHCf experiment is a double arm sampling calorimeter, installed +/-140 m away from the Atlas LHC interaction point. The detectors allow precise measurement of energy and impact point of the neutral particles (mainly photons and neutrons) produced very forward
in the LHC proton-proton interactions, in the pseudorapidity region greater than 8; this measurement is crucial for the...

Their capability to penetrate through large depths of material renders high-energy atmospheric muons a unique probe for geophysical studies. Provided the topography is known, the measurement of the attenuation of the muon flux permits a cartography of density distributions revealing spatial and possibly also temporal variations.

EDELWEISS is a direct search for WIMP dark matter using cryogenic heat-and-ionization germanium detectors. We report the final results of the second stage of the experiment, EDELWEISS-II, obtained with an array of ten 400 g detectors equipped with interleaved electrodes for the rejection of surface events. Limits on the elastic and inelastic cross-sections of spin-independent interactions of...

ATLAS searches for supersymmetry in data from the 2010 and 2011 running of the LHC will be reviewed. These searches were performed in various channels
containing different lepton and jet multiplicities in the final state. Although ATLAS searches for supersymmetry in channels both with and without
missing transverse momentum, this talk will concentrate on the missing transverse momentum...

The self-annihilation, or decay, of dark matter particles could result in significant contributions to cosmic ray fluxes of various kinds, providing a unique opportunity to detect dark matter by means other than through its gravitational interaction. A wealth of observational data, both existing and upcoming, makes these indirect detection channels ever more interesting.
I review the various...

In most of particle dark matter (DM) models, the DM candidate injects sizable fluxes of high-energy electrons and positrons through its annihilations or decays. Emitted in regions with magnetic field, they in turn give raise to a synchrotron radiation, which typically covers radio and infrared bands. We discuss the possibility of detecting signatures of Galactic and extra-galactic DM in the...

MAGIC-I has been operational since 2004 and it already achieved the lowest energy threshold among the current generation of IACTs. In 2009 it was joined by MAGIC-II, and together, in the stereoscopic mode, they allow for the observations of...
