Description
The IceCube experiment is a 1 km3 neutrino observatory instrumenting an array of Digital Optical Modules (DOMs) deep inside the ice at the South Pole. DeepCore, a densely-spaced subarray of DOMs at the bottom central region of IceCube, enables the detection of atmospheric neutrinos with an energy threshold in the GeV range. With a wide range of energies over a large range of baselines, the high statistics data of DeepCore provides a unique opportunity to perform standard neutrino oscillation studies as well as explore various sub-leading Beyond the Standard Model (BSM) physics signatures. We consider a well-motivated minimal extension of the Standard Model by an additional anomaly-free, gauged lepton-number symmetry, such as Le − Lµ or Le − Lτ. These symmetries give rise to flavor-dependent long-range interaction, mediated through a very light neutral gauge boson. For instance, a huge electron number density inside the Sun can generate this long-range potential, which may lead to significant modifications in atmospheric neutrino oscillation probabilities. In this talk, we present the sensitivity of the IceCube DeepCore detector to search for this flavor-dependent long-range interaction potential with a runtime of 9.3 years.
