Consistent origin of matter-antimatter imbalance and dark matter in the early universe

This is an excerpt for media people or science journalists. A good story could be written from my two newly published papers (out of six). My personal goal would be to wake up some of the most relevant experimentalists. This should be a win-win situation and I hope it won’t fall on deaf ears. Here is the plain-English summary of the two published works (arXiv:1902.01837 & arXiv:1904.03835):

Matter-antimatter asymmetry and dark matter as two of the biggest puzzles in the Universe can be consistently and quantitatively understood under a new mirror-matter theory. The new theory assumes that there exist two parallel sectors of particles that share nothing but gravity and it leads to neutral particle oscillations because of slightly broken mirror symmetry. Specifically, neutron and kaon oscillations with new understanding of quark condensation and phase transition processes in the early Universe provide the necessary mechanism. The idea is that kaon oscillations first create a potential amount of matter-antimatter asymmetry at the stage of strange quark condensation. A new topological transition process (coined “quarkiton”) can then preserve the generated matter-antimatter asymmetry. Without such an asymmetry, we would not have lived in a universe of galaxies and stars. In the end, neutron oscillations convert most of the matter to mirror matter which corresponds to the dark matter we have observed today. Under the same framework, another so-called U(1) or strong CP problem that has baffled particle physicists for almost half a century is understood as well.

Most remarkably, the new theory with the same few parameters can explain many of the most celebrated puzzles in physics: dark matter and neutron lifetime anomaly [1], evolution of stars [2], matter antimatter imbalance [3], ultra high energy cosmic rays [4]. In addition, various feasible experiments with current technology are proposed to test the new theory [5]. The most recent development shows the full-fledged theory with an elegant solution for dark energy [6].

As a research professor at Notre Dame, I share 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.
