Search for Coherent Elastic Scattering of Solar B8 Neutrinos in the XENON1T Dark Matter Experiment
2021
We report on a search for nuclear recoil signals from solar $^8$B neutrinos elastically scattering off xenon nuclei in XENON1T data, lowering the energy threshold from 2.6 keV to 1.6 keV. We develop a variety of novel techniques to limit the resulting increase in backgrounds near the threshold. No significant $^8$B neutrino-like excess is found in an exposure of 0.6 t $\times$ y. For the first time, we use the non-detection of solar neutrinos to constrain the light yield from 1-2 keV nuclear recoils in liquid xenon, as well as non-standard neutrino-quark interactions. Finally, we improve upon world-leading constraints on dark matter-nucleus interactions for dark matter masses between 3 GeV/…
Search for inelastic scattering of WIMP dark matter in XENON1T
2021
We report the results of a search for the inelastic scattering of weakly interacting massive particles (WIMPs) in the XENON1T dark matter experiment. Scattering off $^{129}$Xe is the most sensitive probe of inelastic WIMP interactions, with a signature of a 39.6 keV de-excitation photon detected simultaneously with the nuclear recoil. Using an exposure of 0.89 tonne-years, we find no evidence of inelastic WIMP scattering with a significance of more than 2$\sigma$. A profile-likelihood ratio analysis is used to set upper limits on the cross-section of WIMP-nucleus interactions. We exclude new parameter space for WIMPs heavier than 100 GeV/c${}^2$, with the strongest upper limit of $3.3 \time…
Condamnation d’un hôpital pour obstination déraisonnable sur un nouveau-né : réflexion médico-légale et éthique
2011
Resume Une decision du tribunal administratif de Nimes du 2 juin 2009 est venue condamner l’hopital d’Orange a indemnisation pour obstination deraisonnable apres la reanimation d’un enfant, desormais lourdement handicape, ne en etat de mort apparente apres une periode de souffrance fœtale d’environ 30 minutes suivie de 25 minutes de reanimation. Le tribunal n’a retenu aucune faute a l’encontre de l’hopital lors de la prise en charge maternelle. Mais il condamne l’hopital pour obstination deraisonnable, l’equipe medicale ne pouvant ignorer les consequences neurologiques nefastes d’une souffrance fœtale prolongee et la reanimation ayant ete d’une duree excessive. Nous developperons sur le pla…
