Description
The IceCube experiment is a cubic kilometer neutrino observatory at the South Pole which uses an array of Digital Optical Modules (DOMs) deep inside the ice to detect the neutrinos. IceCube has a denser geometry of DOMs at its bottom central region known as DeepCore which enables it to detect GeV energy atmospheric neutrinos. DeepCore provides a unique avenue to explore various tiny Beyond the Standard Model (BSM) physics scenarios with its high statistics data. In this work, we consider a minimal anomaly free extension of the Standard Model by an additional lepton-number symmetry ($L_e - L_\mu$ or $L_e - L_\tau$) which can introduce a very light gauge boson mediating flavor-dependent neutral current long-range interaction. This new interaction may lead to significant modifications in neutrino oscillation probabilities which can be observed in the atmospheric neutrino oscillations data at DeepCore. In this talk, we present the sensitivity of the IceCube DeepCore to put constraints on this flavor-dependent long-range interaction potential with a runtime of 9.3 years.
