Enrique Fernandez-Martinez, Gerardo Giordano, Olga Mena, Irina Mocioiu
TL;DR
This paper demonstrates that high-statistics atmospheric neutrino data collected by IceCube Deep Core can be effectively used to precisely measure neutrino oscillation parameters, turning a background into a valuable signal.
Contribution
It introduces a method to extract neutrino oscillation parameters from atmospheric neutrino data in IceCube, which was previously considered mainly as background.
Findings
High-statistics atmospheric neutrino data enables precise oscillation measurements
IceCube Deep Core can distinguish neutrino oscillation effects from background
The approach improves understanding of neutrino properties
Abstract
The main goal of the IceCube Deep Core Array is to search for neutrinos of astrophysical origins. Atmospheric neutrinos are commonly considered as a background for these searches. We show that the very high statistics atmospheric neutrino data can be used to obtain precise measurements of the main oscillation parameters.
