My 1st mirror matter paper accepted for publication

My 1st paper on n-n’ oscillations and mirror / dark matter is just accepted today for publication in Physics Letters B. After numerous times of rejection, the acceptance finally arrives.

This paper is the first one of several papers on my phenomenological mirror-matter model (M3) and it provides a new understanding of dark matter and neutron lifetime anomaly:

Neutron oscillations for solving neutron lifetime and dark matter puzzles

A model of \(n-n’\) (neutron-mirror neutron) oscillations is proposed under the framework of the mirror matter theory with slightly broken mirror symmetry. It resolves the neutron lifetime discrepancy, i.e., the 1% difference in neutron lifetime between measurements from “beam” and “bottle” experiments. In consideration of the early universe evolution, the \(n-n’\) mass difference is determined to be about \(2\times 10^{-6}\) eV/c\(^2\) with the \(n-n’\) mixing strength of about \(2\times 10^{-5}\). The picture of how the mirror-to-ordinary matter density ratio is evolved in the early universe into the observed dark-to-baryon matter density ratio of about 5.4 is presented. Reanalysis of previous data and new experiments that can be carried out under current technology are discussed and recommended to test this proposed model. Other consequences of the model on astrophysics and possible oscillations of other neutral particles are discussed as well.

I am sharing my ideas and thoughts mainly about mirror matter theory and open science on this blog. Under the new theory, we live in the universe with a mirror (hidden) sector of particles. A perfectly imperfect (minimally broken) mirror symmetry is the key to unlock the beauty and elegance of our universe.
