COVID-19 pandemic has hindered my scientific production quite a bit. But finally my new paper on “invisible decays of neutral hadrons” is finished though it should have been done months ago. It provides precise predictions on invisible decay branching fractions of long-lived neutral hadrons that can be readily measured at existing collider facilities. The idea is that CP violation can be considered as a direct result of spontaneous mirror symmetry breaking at staged quark condensation (e.g., at temperatures of 100GeV – 100 MeV in the early Universe). For a neutral kaon system, it means that the CP and mirror breaking scales, i.e., the mixing strength and mass splitting parameters should be the same.
One piece of news regarding mirror matter studies was published in June, this year by New Scientist as a cover story titled “We’ve seen signs of a mirror-image universe that is touching our own”. I was interviewed and also quoted in this article. But I was not informed that the article was actually centered about Leah Broussard’s experiment at Oak Ridge national laboratory. As a matter of fact, I was not aware of it at all. The ironic part is that her experiment, as far as I understand, will not uncover any new physics if my new model is correct while I was quoted in the article like a theorist endorsing this and other similar experiments.
I was not aware of this article until one of my Chinese friends showed me the Chinese version of the article. Then I read the full English version from my institution’s library (the online version is not free). The article could have been a good one had the author replaced the experiments with, or at least focused on the ones discussed in the APS april meeting this year. Here are the links to the talks on neutron lifetime experiments at the meeting: session C14 and session D14. I wish I could have attended that meeting.
In light of the newly developed model (M3 and SM3 ), if further confirmed, most effort of current dark matter search will be destined to failures. Indeed, there is nothing to detect if there is no direct interaction, however weak, between normal particles and dark (mirror) particles. This makes all the Weakly-Interacting-Massive-Particle-like (WIMP-like) or axion search programs to no avail. However, the advancement of the detection technology with the past efforts including those for the detection of neutrinos could be rekindled to a new life for the studies of mirror matter.
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.
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.
Technology is ready for various laboratory tests on the new mirror-matter model. The predicted new physics could be discovered right around the corner. If you are an experimental physicist, you may be interested in conducting such tests. See arXiv:1906.10262 for details or the following for a brief summary:
