Wavelength-shifting optical modules - Stephan Schulte

Low Energy

Large-scale underground water-Cherenkov neutrino observatories rely on single photon sensors whose sensitive area for Cherenkov photons one wants to maximise. Low dark noise rates and dense module spacing will thereby allow to substantially decrease the energy threshold in future projects. We describe a feasibility study of a novel type of single photon sensor that employs organic...

The km3 simulation package is the standard software suite used by the ANTARES collaboration to simulate the emission and detection of Cherenkov photons. Here, the three programs comprising km3 are described, and the performance of km3's latest revision evaluated. Particular focus is paid to the use of the one-particle approximation, by which Cherenkov emission from hadronic cascades is...

Mr Luigi Antonio Fusco (INFN and University of Bologna)

14/10/2013, 12:40

Fusco - Mu background ORCA

Simulations

A strong background for the observation of atmospheric neutrino induced upgoing muons is due to the presence of wrongly reconstructed muons. A strategy for the rejection of this background is presented, relying on the output of the reconstruction code "reco".

James / Hofestadt - Intrinsic physics limitations

Intrinsic physics limitations

At the characteristic energies (~20 GeV and below) at which ORCA/PINGU will look for hierarchy-dependent effects in the neutrino interaction rate, random fluctuations in the event characteristics will play a significant roll in limiting the accuracy of any reconstruction. In this contribution, the effects of such fluctuations in the determination of the energy and direction of muon tracks and...

Bair Shaybonov (JINR)

15/10/2013, 09:30

Shaybonov - Cascade recon in Baikal

Reconstruction

A new analysis of the data from the NT200 neutrino telescope based on the reconstruction of parameters for high-energy cascades generated in neutrino interactions has yielded new upper limits on the diffuse neutrino fluxes predicted by a number of theoretical models. The upper limit on the all-flavor neutrino flux with an energy spectrum E-2 is 2.9 10-7 GeV cm-2 s-1 ster-1

Mr Thomas Heid (ECAP)

15/10/2013, 10:15

Thomas Heid - Flavor separation

Reconstruction

The talk is about the afforts which are taken to distinguish between track-like events and shower-like events. In ORCA it is necessary to make this decision as the calculations for mass hierarchy determination is based on muon neutrinos.

15/10/2013, 10:30

DeYoung / Groh - Flavor / Particle ID

We will describe a particle identification algorithm based on identification of "superluminal" hits -- photons arriving earlier than expected from propagation of light from a reconstructed cascade vertex.

Thomas Gaisser (University of Delaware)

15/10/2013, 11:30

Gaisser - Nu self-veto

Neutrino Self-Veto

Muons produced in the same event as an atmospheric neutrino will exclude the atmospheric neutrino from a sample of events required to originate inside a fiducial volume of a detector. I will discuss how the veto is evaluated for use in the IceCube High Energy Starting Event analysis.

37. Lowering IceCube's energy threshold for point source searches in the southern sky

Jacob Feintzeig (University of Wisconsin--Madison)

15/10/2013, 11:50

Feintzeig - Intermediate Energy Starting Tracks

Intermediate energy starting tracks

Veto techniques are opening up new doors for point source searches in IceCube. Traditional IceCube point source analyses are only sensitive to PeV-scale fluxes in the southern hemisphere. We demonstrate that extending the “high-energy starting event” veto to lower energies allows IceCube to probe southern sky sources in the 10 TeV – 1 PeV regime. After discussing the event selection and...

Air Cherenkov Surface Veto - Ty DeYoung

Air Cherenkov Surface Veto

Preliminary ideas regarding a surface veto array based on simple imaging air Cherenkov telescopes will be presented. Early studies suggest that cosmic ray primaries responsible for atmospheric neutrinos above an energy threshold of a few TeV could be tagged efficiently.

40. Considerations for a surface veto array and a look at event rates

Albrecht Karle (o=uwmad,ou=Institutions,dc=icecube,dc=wisc,dc=edu)

15/10/2013, 13:45

Karle / Auffenberg - IceVeto

Considerations for surface veto strategies / IceVeto

I will have a brief look at a surface veto array upgrade. Simulated event rates in IceCube suggest that surface veto detectors will add of order 10 muon neutrino events after atmospheric veto cut depending the threshold. Such strategies may offer benefits for lower energy source searches. They need to be compared to other muon neutrino search channels.
