THEORY. “Particle–antiparticle mirror symmetry is also known as charge-conjugation parity-reversal (CP) symmetry; it combines the charge symmetry between particles and their antiparticles with parity (the idea that physical laws should not change in an antimatter mirror world).” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THEORETICAL SUPPORT. “Dark matter In spite of the lack of evidence for Beyond-Standard-Model (BSM) particles from experiments at the Large Hadron Collider (LHC), TeV-scale models of DM particles are nicely supported by cosmological constraints.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

RULE BREAKERS. “It was long thought that antiparticles would behave in the same way as particles in a mirror world made of antimatter, but since the 1960s we have known that quarks and antiquarks break this particle–antiparticle mirror symmetry.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

ANTIMATTER. “For each elementary particle, there is an antiparticle that has the same properties but opposite charge. The best-known example is the antielectron, or positron.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE LEGO KIT. “All visible matter in the Universe is made of fundamental building blocks, the elementary particles. The group of particles known as fermions consists of two types: quarks, which make up protons and neutrons; and leptons, namely, the electron, muon, tau particle and neutrino.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

“The Sombrero Galaxy as never seen before? Discovered by Pierre Méchain at the end of the 18th century, it is one of the sharpest and most spectacular images captured by the Hubble Space Telescope, especially because the angle at which it is seen from our planet creates a tremendously impressive visual effect.

INTUITIVE BIAS. “One reason we consider Newton brilliant is that in order to come up with his second law he had to ignore some data. He had to imagine, for example, that things were falling in a vacuum, free of the interfering effects of air resistance.” https://www.theguardian.com/technology/2022/jan/09/are-we-witnessing-the-dawn-of-post-theory-science?CMP=Share_iOSApp_Other View in LinkedIn

SURPRISE. “In a mirror world, antiparticles should behave in the same way as particles. But it emerges that leptons — neutrinos, electrons and their more exotic cousins — might not obey this expected pattern.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

TOOL. “Leptonic CP violation is elusive, but can be searched for using neutrinos. These fundamental particles are remarkably reluctant to interact with ordinary matter, making them very hard to detect. They are the least understood known particle.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

ANTICIPATION. “The discovery of substantial leptonic CP violation would be groundbreaking. Its observation, together with evidence that a quantity known as lepton number has been violated (that is, not conserved), would provide strong circumstantial evidence for leptogenesis as the origin of the matter–antimatter imbalance.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
