We discuss here the characteristics of event detected in Mont Blanc Underground Neutrino Observatory on February 23, 1987, consisting 5 interactions recorded during 7s. The measured energies pulses, duration burst, and advance detection time comparison with first optical observations give evidence that can be explained terms neutrinos emitted stellar collapse Large Magellanic Cloud.
We report the observation of a steepening in cosmic ray energy spectrum heavy primary particles at about 8×10(16) eV. This structure is also seen all-particle spectrum, but less significant. Whereas "knee" 3-5×10(15) eV was assigned to light masses by KASCADE experiment, new found KASCADE-Grande experiment caused primaries. The result obtained independent measurements charged particle and muon components secondary extensive air showers range 10(16) 10(18) data are analyzed on single-event...
We present the first results of searches for axions and axion-like-particles with XENON100 experiment. The axion-electron coupling constant, $g_{Ae}$, has been probed by exploiting axio-electric effect in liquid xenon. A profile likelihood analysis 224.6 live days $\times$ 34 kg exposure shown no evidence a signal. By rejecting larger than $7.7 \times 10^{-12}$ (90\% CL) solar axion search, we set best limit to date on this coupling. In frame DFSZ KSVZ models, exclude QCD heavier 0.3...
Recent results of the KASCADE-Grande experiment provided evidence for a mild knee-like structure in all-particle spectrum cosmic rays at $E={10}^{16.92\ifmmode\pm\else\textpm\fi{}0.10}\text{ }\text{ }\mathrm{eV}$, which was found to be due steepening flux heavy primary particles. The combined components light and intermediate masses compatible with single power law energy range from ${10}^{16.3}$ ${10}^{18}\text{ }\mathrm{eV}$. In this paper, we present an update analysis by using data...
The amplitude and phase of the cosmic-ray anisotropy are well established experimentally between 1011 eV 1014 eV. study their evolution in energy region 1014–1016 can provide a significant tool for understanding steepening ("knee") primary spectrum. In this Letter, we extend EAS-TOP measurement performed at E0 ≈ to higher energies by using full data set (eight years taking). Results derived about 4 × compared discussed. Hints increasing change above reported. significance observation propagation is
The low-background, VUV-sensitive 3-inch diameter photomultiplier tube R11410 has been developed by Hamamatsu for dark matter direct detection experiments using liquid xenon as the target material. We present results from joint effort between XENON collaboration and company to produce a highly radio-pure photosensor (version R11410-21) XENON1T experiment. After introducing its components, we show methods of radioactive contamination measurements individual materials employed in production....
KASCADE and KASCADE-Grande were multi-detector installations to measure individual air showers of cosmic rays at ultra-high energy. Based on data sets measured by KASCADE-Grande, 90% C.L. upper limits the flux gamma-rays in primary ray are determined an energy range ${10}^{14} - {10}^{18}$ eV. The analysis is performed selecting with a low muon content as expected for gamma-ray-induced compared induced energetic nuclei. best limit fraction total obtained $3.7 \times {10}^{15}$ eV $1.1...
XENON is a dark matter direct detection project, consisting of time projection chamber (TPC) filled with liquid xenon as medium. The construction the next generation detector, XENON1T, presently taking place at Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It aims sensitivity to spin-independent cross sections 2 · 10-47 c for WIMP masses around 50 GeV2, which requires background reduction by two orders magnitude compared XENON100, current detector. An active system that able tag muons...
LOPES is a digital radio interferometer located at Karlsruhe Institute of Technology (KIT), Germany, that measures emission from extensive air showers MHz frequencies in coincidence with KASCADE-Grande. In this article, we explore method (slope method) leverages the slope measured lateral distribution to reconstruct crucial attributes primary cosmic rays. First, present an investigation on basis pure simulations. Second, directly apply measurements. Applying simulations, obtain uncertainties...
Laboratory experiments searching for galactic dark matter particles scattering off nuclei have so far not been able to establish a discovery. We use data from the XENON100 experiment search interacting with electrons. With no evidence signal above low background of our experiment, we exclude variety representative models that would induce electronic recoils. For axial-vector couplings electrons, cross-sections 6x10^(-35) cm^2 particle masses m_chi = 2 GeV/c^2. Independent halo, leptophilic...
Analyzing measurements of the LOPES antenna array together with corresponding CoREAS simulations for more than 300 measured events energy above 1017 eV and zenith angles smaller 45o, we find that radio wavefront cosmic-ray air showers is approximately hyperbolic shape. The predict a slightly steeper towards East West, but this asymmetry negligible against measurement uncertainties LOPES. At axis distances ≳ 50 m, can be approximated by simple cone. According to simulations, cone angle...
