Oral contribution

The XENON program aims at the direct detection of dark matter WIMPs with liquid xenon as target and detecting material. With detectors of increasing target mass and decreasing background, XENON has achieved competitive limits on WIMP-nucleon interaction couplings, but also on axions and axion-like particles. The XENON100 detector has been ongoing at the Laboratori Nazionali del Gran Sasso in...

442. The XMASS Experimental Program and its Current Implementation

Oral contribution

XMASS is an experimental program at the Kamioka Observatory in Japan designed for low energy, low background dark matter searches and neutrino physics. The core technology is a self shielding single-phase liquid xenon detector optimized for maximum scintillation light collection. In this talk we describe its current implementation and discuss its general performance after its 2013 refurbishment.

949. Results from the fiducial volume analysis of the XMASS-I dark matter data

Oral contribution

XMASS-I, the first phase of the XMASS project, is a direct detection dark matter experiment using 832 kg of liquid xenon. The key idea to reduce the background at low energies in XMASS is to use liquid xenon itself as a shield. In this analysis the clean core of the 832 kg liquid xenon volume is used as sensitive fiducial volume by eliminating the volume near the wall which suffers from beta...

Oral contribution

The DAMIC (Dark Matter in CCDs) experiment uses  high resistivity scientific grade CCDs  to search for dark matter.  The CCD's low electronic noise allows an unprecedently low energy threshold of few tens of eV that makes it possible to detect silicon recoils resulting from interactions of low mass WIMPs. In addition the CCD's high spatial resolution and the excellent energy response ...

320. Search for Dark Matter annihilations in the Sun using the completed IceCube neutrino telescope.

DM-EX

Oral contribution

If Dark Matter consists of Weakly Interacting Massive Particles (WIMPs), these might be gravitationally captured in the Sun where they could self-annihilate into standard model particles. Terrestrial neutrino detectors such as IceCube can observe this as an enhanced neutrino flux in the direction of the Sun. Sensitivity has improved with respect to previous searches due to better analysis...

243. The indirect search for dark matter with the ANTARES neutrino telescope

Christoph Tönnis (Universitat de Valencia)

DM-EX

Oral contribution

The indirect search for dark matter is a topic of utmost interest in neutrino telescopes. The ANTARES detector is located on the bottom of the Mediterranean Sea 40 km off the southern french coast. ANTARES has been taking data since 2007 when the first half of the detector was installed. In this talk the results of the different analyses for dark matter signals from different potential...
