beyond Standard Model
Nature’s supersymmetry (SUSY) is not what most physicists have thought about. It is not making a copy of all existing particles and giving these superparticles some fancy names like something-ino or s-otherthing.
The big mistake on SUSY has been to confuse some properties of SUSY with those of mirror symmetry which has not drawn deserved attention from the physics community. It is actually the mirror symmetry that makes a mirrored copy of particles in our known sector.
The newly proposed phenomenological mirror-matter model (M3) has just been developed into a full-fledged theory – extended Standard Model with Mirror Matter (SM3). Dark energy is simply understood as the leftover vacuum energy due to the spontaneous mirror symmetry breaking.

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:

It’s been half a year since I posted the 1st of my papers about mirror-matter on arXiv on the Chinese New Year day of 2019 (BTW, year of the pig). Here is the brief summary of my work.
Understanding the mirror sector of the Universe
–to solve the puzzles of dark matter, baryogenesis, neutron lifetime, and star evolutionOriginated from Lee and Yang’s seminal work on parity violation, a rather exact mirror matter model is proposed using spontaneous mirror symmetry breaking, which results in oscillations of neutral particles [1]. As it turns out, neutron-mirror neutron (n-n’) oscillations become one of the best messengers between the ordinary and the mirror worlds. The new n-n’ model resolves the neutron lifetime discrepancy, i.e., the 1% difference between measurements from “Beam” and “Bottle” experiments. The picture of how the mirror-to-ordinary matter density ratio is evolved in the early universe into today’s observed dark-to-baryon matter density ratio (~5.4) is gracefully demonstrated. A new theory of evolution and nucleosynthesis in stars [2] based on the new model of n-n’ oscillations presents remarkable agreement between the predictions and the observations. For example, progenitor mass limits and structures for white dwarfs and neutron stars, two different types of core collapse supernovae (Type II-P and Type II-L), synthesis of heavy elements, pulsating phenomena in stars, etc, can all be easily and naturally explained under the new theory.
More intriguingly, a natural extension of the new model applying kaon oscillations in the early universe shows a promising solution to the long-standing baryon asymmetry problem with new insights for the QCD phase transition and B-violation topological processes [3]. A consistent picture for the origin of both baryon asymmetry and dark matter can then be depicted with kaon and neutron oscillations under the new model. In addition, puzzles in ultrahigh energy cosmic rays have also been explained under the new mirror-matter model [4]. Last but not least, various laboratory measurements using current best technology are proposed to test the model and the extended CKM matrix [5].
