Time Modulation of K-Shell Electron Capture Decay Rates of H-Like Heavy Ions and Neutrino Masses

TL;DR

This paper investigates how the decay rates of H-like heavy ions' electron capture are modulated over time and uses this data to estimate neutrino masses, considering Coulomb interaction effects.

Contribution

It introduces a method to determine neutrino masses from time-modulated decay rates, accounting for Coulomb corrections, which is a novel approach in neutrino physics.

Findings

Neutrino masses are estimated from decay rate modulations.

Coulomb interactions significantly affect neutrino mass calculations.

Time modulation data provides new insights into neutrino properties.

Abstract

We calculate the neutrino masses, using the experimental data on the periods of the time modulation of the K-shell electron capture (EC) decay rates of the H-like heavy ions, measured at GSI. The corrections to neutrino masses, caused by interaction of massive neutrinos with the strong Coulomb field of the daughter ions, are taken into account.
