Addendum to `Combined Analysis of Neutrino Decoherence at Reactor Experiments'

TL;DR

This paper updates constraints on neutrino decoherence using the latest RENO and Daya Bay data, showing minimal improvement when combined with KamLAND data, thus refining our understanding of neutrino wave-packet separation effects.

Contribution

It provides an updated analysis of neutrino decoherence constraints incorporating the final data sets from RENO and Daya Bay experiments.

Findings

Individual bounds from Daya Bay and RENO improved

Combined fits still dominated by KamLAND data

Minimal overall improvement in decoherence constraints

Abstract

We update our analyses to constrain neutrino decoherence induced by wave-packet separation with RENO and Daya Bay data, now including the final data sets of the two experiments. We find that while the individual bounds from Daya Bay and RENO data improve relative to our original estimates, the combined fits are still dominated by KamLAND data and are only minimally improved.
