Low-scale leptogenesis with three heavy neutrinos

Marco Drewes, Valerie Fiona Domcke, Juraj Klaric

Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous studies invoking only two heavy neutrinos to the case of three heavy neutri ...

Energy reconstruction methods in the IceCube neutrino telescope

Matthias Wolf, Mark Tobin, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

Accurate measurement of neutrino energies is essential to many of the scientific goals of large-volume neutrino telescopes. The fundamental observable in such detectors is the Cherenkov light produced by the transit through a medium of charged particles cr ...

Search for neutrino-induced particle showers with IceCube-40

Matthias Wolf, Mark Tobin, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

We report on the search for neutrino-induced particle showers, so-called cascades, in the IceCube-40 detector. The data for this search were collected between April 2008 and May 2009 when the first 40 IceCube strings were deployed and operational. Three co ...

Playing quantum hide-and-seek with the muon: localizing muon stopping sites

Nicola Marzari

The most fundamental limitations of a muon-spin relaxation experiment can be the lack of knowledge of the implantation site of the muon and the uncertainty about the muon's perturbation of its host. Here we review some of the work done on the 'muon site pr ...

Measurement of the atmospheric neutrino energy spectrum from 100 GeV to 400 TeV with IceCube

Matthias Wolf, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

A measurement of the atmospheric muon neutrino energy spectrum from 100 GeV to 400 TeV was performed using a data sample of about 18 000 up-going atmospheric muon neutrino events in IceCube. Boosted decision trees were used for event selection to reject mi ...

The IceCube data acquisition system: Signal capture, digitization, and timestamping

Xiaoxia Bai

IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optic ...

First Neutrino Point-Source Results From The 22 String Icecube Detector

Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen, Levent Demirörs

We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-2008 with 22 strings of the IceCube detector (approximately one-fourth of the planned total) and 275.7 days of live time. The final sample of 511 ...
