“…The warping of the top meshes (inducing a variation in the width of the gas gap between the anode and the liquid-gas interface), the absorption of electrons by residual impurities as they drift towards the gas region, as well as solid angle effects, lead to a position-dependent S2 signal. These signals are thus corrected in 3 dimensions, using various calibration data, as detailed in [7,15], with the corrected quantities denoted as cS1 and cS2, defined in [15].…”

“…The horizontal position, (x, y), of the interaction site is reconstructed from the position of the S2 shower, while the depth of the interaction, z, is given by the drift time measurement. The TPC thus yields a three-dimensional event localization, with an (x, y) resolution of <3 mm (1 σ), and a z resolution of <0.3 mm (1 σ), enabling to reject the majority of background events via fiducial volume selections [7]. The ratio S2/S1 provides the basis for distinguishing between nuclear recoils (NRs), as induced by fast neutrons and expected from elastic WIMP-nucleus scatters, and electronic recoils (ERs) produced by β-and γ-rays.…”

We present the first constraints on the spin-dependent, inelastic scattering cross section of Weakly Interacting Massive Particles (WIMPs) on nucleons from XENON100 data with an exposure of 7.64×10 3 kg day. XENON100 is a dual-phase xenon time projection chamber with 62 kg of active mass, operated at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy and designed to search for nuclear recoils from WIMP-nucleus interactions. Here we explore inelastic scattering, where a transition to a low-lying excited nuclear state of 129 Xe is induced. The experimental signature is a nuclear recoil observed together with the prompt de-excitation photon. We see no evidence for such inelastic WIMP-129 Xe interactions. A profile likelihood analysis allows us to set a 90% C.L. upper limit on the inelastic, spin-dependent WIMP-nucleon cross section of 3.3×10 −38 cm 2 at 100 GeV/c 2 . This is the most constraining result to date, and sets the pathway for an analysis of this interaction channel in upcoming, larger dual-phase xenon detectors. *

“…The results are shown in figure 26 where we plot the spin-independent cross section as a function of m KK for five choices of ΛR (in blue) as well as various bounds from experiences: Zepelin [32], Edelweiss + CDMS combined data [33], Xenon limits from 2011 [34] and 2012 [35] as well as projection limits in Xenon for 2017 extracted from DMTools. The numerical values for ΛR = 2, 4, 6, 8, and 10 are given in table 12.…”

Abstract:The real projective plane is a compact, non-orientable orbifold of Euler characteristic 1 without boundaries, which can be described as a twisted Klein bottle. We shortly review the motivations for choosing such a geometry among all possible two-dimensional orbifolds, while the main part of the study will be devoted to dark matter study and limits in Universal Extra Dimensional (UED) models based on this peculiar geometry. In the following we consider such a UED construction based on the direct product of the real projective plane with the standard four-dimensional Minkowski space-time and discuss its relevance as a model of a weakly interacting Dark Matter candidate.One important difference with other typical UED models is the origin of the symmetry leading to the stability of the dark matter particle. This symmetry in our case is a remnant of the six-dimensional Minkowski space-time symmetry partially broken by the compactification. Another important difference is the very small mass splitting between the particles of a given Kaluza-Klein tier, which gives a very important role to co-annihilation effects. Finally the role of higher Kaluza-Klein tiers is also important and is discussed together with a detailed numerical description of the influence of the resonances.

“…The scattering media in this type of detectors is the liquid Xenon (A Xe 131) and the recoil ionization can be detected by scintillation and/or charge collection. The Xenon100 detector, a combination of TPC for the detection of the ionization and of PMT's for the detection of the scintillation light, has been constructed at the LNGS starting from 2007 [39]. One advantage of this technique is the possible accurate measurement of the rise time of the pulse of charge, that allows a discrimination of long tracks from the short tracks, expected in case of nuclear recoils [40].…”
