New limits on WIMP search with large-mass low-radioactivity NaI(Tl) set-up at Gran Sasso

Improved limits on WIMP search have been obtained by the pulse shape analysis of the data collected with a large-mass low-radioactivity NaI(Tl) set-up at Gran Sasso National Laboratory.

Charge conservation and electron lifetime: Limits from a liquid xenon scintillator

New limits on the mean lifetime of the electron for decay into non-ionizing particles have been achieved by using a low activity liquid xenon scintillator at the Gran Sasso National Laboratory.

Limits on WIMP-129Xe inelastic scattering

Abstract Limits on WIMP- 129 Xe nucleus inelastic scattering have been achieved by using a low activity liquid xenon scintillator at the Gran Sasso National Laboratory. Signigicant improvements have been reached.

Search for WIMPs with enriched xenon at Gran Sasso

SummaryA low-activity liquid-xenon scintillator is running at the Gran Sasso National Laboratory of INFN using liquid Kr-free xenon enriched at 99.5% in129Xe. The result of adark matter direct search—looking also for the annual modulation effect—is presented. Preliminary exclusion plots both for coherent and spin-dependent coupled WIMPs are evaluated.

A MULTITON LOW ACTIVITY NAI(TL) DETECTOR FOR UNDERGROUND PHYSICS

This paper presents the main physical goals reachable with a large mass and extremely radiopure NaI(Tl) set-up such as the detection of very low interacting rate Dark Matter candidates and of solar neutrinos.

On the possibility to measure neutrino magnetic moment down to 10−11μB

Abstract We discuss a possibility to search for a neutrino magnetic moment in the range 10 −10 -10 −11 μ B using a 147 Pm antineutrino source and a large mass high radiopurity NaI(TI) detector deep underground

Response of a “large” CaF2(Eu) scintillator at low temperature

Abstract The response of a 54 g CaF2(Eu) scintillator as a function of the temperature has been studied down to 1 K.

Improved limits on strongly interacting massive particles with NaI(Tl) scintillators

Abstract We report here the results of an improved set-up for SIMP detection. The sensitivity obtained in 479 days of running time gives an order of magnitude improvement on the previously reported results.
