Oscillation tomography of the Earth with solar neutrinos and future experiments

Dr Pouya Bakhti (IPM)

Description

We study in details the Earth matter effects on the boron neutrinos
from the Sun using recently developed 3D models of the Earth.
The models have a number of new features of the density profiles,
in particular, substantial deviation from spherical symmetry.
The nadir angle ($\eta$) dependences of $A_{ND}$ are computed for future detectors DUNE, THEIA, Hyper-Kamiokande and MICA
at the South pole.
Perspectives of the oscillation tomography of the Earth
with the boron neutrinos are discussed. Next generation of detectors
will establish the integrated day-night asymmetry with high confidence level.
They can give some indications of the $\eta-$
dependence of the effect, but will discriminate among different models
at most at the $(1 - 2)\sigma$ level.
For the high level discrimination, the MICA-scale experiments are needed. MICA can
detect the ice-soil borders and perform unique tomography of Antarctica.

Mini-abstract

We've studied the potential of future neutrino observatories to distinguish between 3D earth models.
