Description
The IceCube neutrino observatory is nearly complete, with 79 of the
planned 86 strings deployed. Projected to be fully completed next
austral summer, it will cover an instrumented volume of 1km^3 of deep
ice, tagging neutrinos by detecting the Cerenkov light emissions of
neutrino-induced leptons and hadronic showers.
We present a model-dependent point source search for a neutrino
signal from LS I +61 303, a high mass X-ray binary system. The model
considered here is based on MWL observations, notably Fermi, and assumes
that the broad band activity of the system is due to high energy
protons interacting with the dense matter and radiation field of the
massive star. Making basic assumptions on the geometry of the binary
system, the model predicts the time-dependence of the neutrino
emissions.
These predictions are used to constrain the neutrino signal
search. Assuming their validity, this alternative model-dependent
approach has an enhanced discovery potential and is complementary to
generic time-dependent and steady point sources searches. The model
and the analysis method will be described, and sensitivities in addition to
results based on the 22 and 40 string IceCube configurations will be
presented.
