Proposed TRV Measurement via L-nL Neutrino Oscillations

TL;DR

This paper extends a neutrino experiment to measure time reversal violation by considering Earth's curvature and matter effects, proposing a modified detector setup for improved results.

Contribution

It introduces a novel approach that accounts for Earth's curvature and matter effects, enhancing the existing L-2L neutrino TRV measurement experiment.

Findings

Earth's curvature significantly affects long baseline neutrino experiments.

Matter effects disappear at extended baselines, simplifying analysis.

Proposes a modified MINOS detector setup at 2L for better measurement accuracy.

Abstract

This is an extension of the L-2L experiment for measurement of time reversal violation (TRV) proposed in a recent publication. The main new aspects are taking into account the curvature of the earth's surface for long baseline neutrino beams, and recognizing that the matter effects disappear when the baseline is extended. A slight modification of the MINOS project, with a new detector at 2L, is proposed.
