## The new website MirrorUniverse.org is up and running

The website of mirroruniverse.org dedicated for the studies of the new mirror matter theory and its test is now up and running. Content-wise, I still have a lot to do and I’ll slowly get it up to date. If you’d like to participate in forum discussion there or make other comments at the site, you need to register. The best (recommended) way to register/login is through the authentication with ORCiD which provides an open ID for all scholars. Here is the link on this how-to if you need more details.

I still need lot of help on the other website: openarxiv.org. In particular, we need people who have experience in developing ePrint platforms or softwares like eprints.org, biorxiv.org, etc. Please contact me if you’d like to help.

## Volunteers are needed for graphic and web design of two websites

Two websites are under construction: mirroruniverse.org and openarxiv.org. We need volunteers who are experienced in graphic and web design to join the team for building these two websites. Feel free to contact me at <wtan AT nd.edu> if you are interested or have further questions.

## New chiral electron-hole pairing mechanism for non-BCS superconductivity

Motivated by the ideas from the NJS model and the concept of staged chiral quark condensation developed in mirror matter theory, I ventured into superconductivity and fortunately developed a novel microscopic pairing mechanism for non-BCS superconductivity. It took me the entire summer and more to reacquaint myself with BCS superconductivity and associated condensed matter physics and I have to immerse myself in the extensive literature on superconductivity accumulated over the past decades.

## Mirror Symmetry for New Physics beyond the Standard Model in 4D Spacetime

Finally, my most recent work on “Mirror Symmetry for New Physics beyond the Standard Model in 4D Spacetime” got published about a week ago in Symmetry 2023, 15(7), 1415. Unfortunately, it did not get much attention it deserves or as I hoped, in particular, no attention from any string theorists. I wish some string theorists will read it and continue to work on these exciting ideas.

## An invited review: neutron lifetime anomaly and mirror matter theory

It still feels like yesterday. Almost exactly four years ago, also around Chinese New Year, I finished my first paper (or to be exact, two) on the new mirror matter theory. Now I just finished my first invited review paper, which exactly details the original motivations on solving the puzzles of neutron lifetime in my first published paper. It feels like I just completed the circle. So many thanks for Dr. Ben Grinstein’s invitation. I’ve been trying to write a review on mirror matter theory and related experiments and observations for a long time. But it never came through. Ben’s invitation has really pushed me to finish this review paper earlier. It is not the full review paper I have imagined, but still a very important part of it. It focuses on the unique perspectives in the analysis of the neutron lifetime anomaly and the CKM unitarity issue, which have been mostly overlooked by the mainstream. It does not present the full picture and details of mirror matter theory. Instead, it gives the details of the phenomenological $n-n’$ oscillation model, and presents exactly how it can explain the above puzzles and how we can test its unique predictions in laboratory experiments.

Here is the paper: Neutron lifetime anomaly and mirror matter theory

## A new milestone paper on mirror matter theory

After procrastinating for almost a year, I finally finished this paper. It is going to be recognized as a new milestone on mirror matter studies. In particular, amazing connections between string theory and new supersymmetric mirror models are established. Mirror symmetry as a fundamental concept is deeply examined. Based on mathematical results from string theory, we can finally put these mirror models on a firmer and self-consistent ground and can really explain an impressive list of puzzles in fundamental physics and cosmology. Without further ado, here it is:

## First experimental work to test my mirror oscillation model

The first experimental paper by BESIII collaboration (motivated under new mirror oscillation model) has just been published: Search for invisible decays of the Λ baryon. It was the first direct test of my idea on neutral hadron oscillations. It gives an upper limit of the invisible decay branching fraction for the Λ baryon: <7.4×10^{−5} , which is consistent with my model. Unfortunately, it is not sensitive enough yet to reach the level of my prediction in the new model: 4.4×10^{−7}. I hope that more experimental works will be coming on invisible decays of other hadrons like K^{0}_{L} and K^{0}_{S}. I wish that people in the business of neutron lifetime measurements could have done much more convincing tests earlier.

## A crackpot’s counter-statement

Some physicists have labeled me as a crack pot when considering my works on the new theoretical framework of mirror matter theory. However, I disagree in the spirit of scientific principles. With three papers published in esteemed journals, seven invited seminars by unrelated people (or more than 10 in total), and grant-seeking in collaboration with several different groups, I don’t think that it is fair to categorize my work on this topic as crackpottery. It is not, especially when considering the unique concrete predictions from my new model that can be readily tested in the laboratory using existing technologies.

## Future of the new mirror matter theory

The new mirror matter theory has only a very rough framework with many of its aspects waiting to be greatly improved and further developed as a nascent research direction. In particular, its mathematical rigor and foundations have yet to be established. Relevant new mathematical tools and approaches are desired to be implemented in the new theory. Theoretical efforts in the past several decades on fundamental physics, especially on topological quantum field theory, string theory, and quantum gravity, need to be merged into the new theoretical framework under the guidance of the newly proposed first principles. Most importantly, the neutral hadron oscillation effects predicted by the new theory are ready to be experimentally tested in laboratory, and it is time for more observation and simulation works in astronomy and cosmology under the consideration of the new theory to be conducted.

As presented below, I’d like to say a few words on the future direction of the new theory to interested mathematicians and physicists.
