A Bayesian technique for improving the sensitivity of the atmospheric neutrino L/E analysis
چکیده انگلیسی

This paper outlines a method for improving the precision of atmospheric neutrino oscillation measurements. One experimental signature for these oscillations is an observed deficit in the rate of νμνμ charged-current interactions with an oscillatory dependence on Lν/EνLν/Eν, where LνLν is the neutrino propagation distance and EνEν is the neutrino energy. For contained-vertex atmospheric neutrino interactions, the Lν/EνLν/Eν resolution varies significantly from event to event. The precision of the oscillation measurement can be improved by incorporating information on Lν/EνLν/Eν resolution into the oscillation analysis. In the analysis presented here, a Bayesian technique is used to estimate the Lν/EνLν/Eν resolution of observed atmospheric neutrinos on an event-by-event basis. By separating the events into bins of Lν/EνLν/Eν resolution in the oscillation analysis, a significant improvement in oscillation sensitivity can be achieved.
