The status of supersymmetry | symmetry magazine
WEBJan 12, 2021 · Supersymmetry more than doubles the number of particles in the Standard Model. The particles we currently know to exist can be divided into two categories: fermions and bosons. In supersymmetric theories, each particle has an as-yet undiscovered “superpartner” with many similar properties. Fermions are paired with bosons and vice …
The Standard Model of Particle Physics | symmetry magazine
WEBThe Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make up the chemical elements, along with any other particles that cannot be broken down into any smaller pieces. The complete Standard Model took a ...
Symmetry Series: The Quantum Ecosystem
WEBJan 11, 2022 · Looking at a new quantum revolution. This month, Symmetry presents a series of articles on the past, present and future of quantum research—and its many connections to particle physics, astrophysics and computing. 01/11/22.
John Bahcall: Godfather of solar neutrinos | symmetry magazine
WEB4 days ago · Bahcall, already a well-respected theorist, calculated the expected solar neutrino flux, creating the Standard Solar Model, and together he and Davis proposed a way to find solar neutrinos—build a huge steel tank deep underground in a gold mine and fill it with 100,000 gallons of chlorine. Davis built the experiment in 1965 in the Homestake ...
The particle physics of you | symmetry magazine
WEBAbout 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. While most of the cells in your body regenerate every seven to 15 years, many of the particles that make up those cells have actually existed for millions of millennia.
Five mysteries the Standard Model can’t explain
WEBOct 18, 2018 · The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. It mathematically lays out the 17 building blocks of nature: six quarks, six leptons, four force-carrier particles, and the Higgs boson. These are ruled by the electromagnetic, weak and strong forces.
Beyond the Standard Model | symmetry magazine
WEBFeb 22, 2022 · The Standard Model is one of the most well-tested theories in particle physics. But scientists are searching for new physics beyond it. Humans have always sought to understand the essence of the world around them. Ancient civilizations believed everything was composed of basic constituents like earth, air, water and fire; in the …
What we know about dark matter | symmetry magazine
WEBThe fact that so much dark matter still seems to be around some 13.7 billion years later tells us right away that it has a lifetime of at least 10 17 seconds (or about 3 billion years), Toro says. But there is another, more obvious clue that the lifetime of dark matter is much longer than that: We don’t see any evidence of dark matter decay.
