Atmospheric neutrinos in Soudan 2

allows a measurement which is independent of an absolute ux or exposure calculation. Soudan 2 is an iron calorimeter with di erent experimental systematics from the water Cherenkov detectors and with a di erent geometry and detection technique from from the Frejus experiment. A large veto shield placed against the cavern wall allows the identi cation of particles entering the detector from the ...

Atmospheric neutrino interactions in Soudan - 2 ∗

A new measurement of the atmospheric νµ/νe ratio-of-ratios, 0.61 ± 0.15 ± 0.05, has been obtained using a 3.2-kty exposure of the Soudan-2 underground detector. This measurement, based upon neutrino reactions in an iron tracking calorimeter of honeycomb-lattice geometry, is in agreement with the anomalously low value reported by the underground water detectors.

Tumeur de Frantz: deux nouveaux cas

A travers cet article, nous détaillons les caractéristiques clinico-pathologiques et discutons l'histogenèse de la tumeur de Frantz. Deux patients opérés pour tumeur de Frantz. Ils ont eu un traitement chirurgical seul. L'étude morphologique était couplée à un examen immuno-histochimique (IHC) utilisant les anticorps anti CD10, antivimentine, anti-énolase neuronale spécifique (NSE), anti-synapt...

Neutrino Oscillation Effects in Soudan-2 Upward-stopping Muons

Upward-going stopping muons initiated by atmospheric νμ and νμ interactions in the rock below the Soudan 2 detector have been isolated, together with a companion sample of neutrinoinduced single muons, created within the detector, which travel downwards and exit. The downward-going sample is consistent with the atmospheric-neutrino flux prediction, but the upward-going sample exhibits a sizeabl...
