Density vs distance for the DUNE beam from two recent geology density maps

TL;DR

This paper compares different geological density maps to assess their impact on neutrino beam modeling from Fermilab to Sanford Lab, highlighting the importance of accurate density data for neutrino experiments.

Contribution

It introduces a comparison of recent and older geological density maps to evaluate their influence on neutrino path density calculations.

Findings

Recent density maps differ significantly from older data.

Density variations affect neutrino oscillation modeling.

Comparison informs better selection of geological data for experiments.

Abstract

The densities passed through for neutrinos going from Fermilab to Sanford lab are obtained using two recent density tables, crustal [1] and Shen-Ritzwoller[2], as well as the values from an older table PEMC[3].
