Speaker: Jessica Dunmore, Oxford

Title: Patterns in SNO

Abstract: I will present results from the Salt Phase of the Sudbury Neutrino Observatory. In this phase, NaCl was added to the heavy water of SNO to enhance the detection of neutrons.   This creates a difference between the topography of the neutron and electron signals.  I will show how a parameterization of the isotropy of events may be used to statistically separate the two signals. From the neutron signal, we derive a model-independent measure of the flux of Boron-8 solar neutrinos.  The implications of the result will be discussed in the context of neutrino oscillations.
