The deconstructed Standard Model equation - symmetry magazine
网页The deconstructed Standard Model equation. 07/28/16. By Rashmi Shivni. The Standard Model is far more than elementary particles arranged in a table. The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used to describe particle properties, such as mass, charge and spin.

网页LZ experiment sets new record in search for dark matter. New results from the world’s most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe’s invisible mass. 08/20/24.
How do neutrinos get their mass? | symmetry magazine
网页Neutrinos are a type of fundamental particle known as a fermion. All other fermions, such as leptons and quarks, gain their mass through their interactions with the Higgs boson. But neutrinos don’t seem to follow that trend. Physicists have proposed hundreds of theories for how neutrinos might get their mass, and everyone has their favorite.
Eight things you might not know about light - symmetry magazine
网页Here are eight enlightening facts about photons: 1. Photons can produce shock waves in water or air, similar to sonic booms. Nothing can travel faster than the speed of light in a vacuum. However, light slows down in air, water, glass and other materials as photons interact with atoms, which has some interesting consequences.
The status of supersymmetry - symmetry magazine
网页2021年1月12日 · 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 …
What is a photon? - symmetry magazine
网页What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible packets of electromagnetic energy. If you are reading this article on a screen or a page, streams of photons are carrying the images of the words to your eyes. In science, photons are used for more than just illumination.
Neutrino invention - symmetry magazine
网页Neutrino invention. 03/01/07. By Kurt Riesselmann. Wolfgang Pauli postulated the existence of a neutral, light-weight particle that could save the fundamental law of the conservation of energy. Wolfgang Pauli, at age 30, had a bold idea on how to solve a perplexing problem in nuclear physics. To explain the apparent disappearance of energy in ...
Ears around the world are on The Coldest Case - symmetry magazine
网页2024年3月5日 · A podcast from the Interactions Collaboration, Particle Mysteries, offers a new way to learn about the puzzling form of matter that holds our universe together, with a four-episode arc titled The Coldest Case. The Coldest Case grew out of Dark Matter Day, a global initiative to engage the public in the worldwide search for this invisible substance.
The secret of Picasso’s paint | symmetry magazine
网页2016年7月28日 · The secret of Picasso’s paint. 01/07/13. By Jessica Orwig. Argonne National Laboratory proves that Pablo Picasso created some of his masterpieces using high-grade house paint. Although he was one of the few artists who attained wealth from his trade, Pablo Picasso used inexpensive, common house paint for some of his works.
Semiconductors - symmetry magazine
网页Semiconductors. Accelerator-powered ion implantation proves key to advances in integrated circuits. Particle accelerators earned an important place on the semiconductor assembly line decades ago, and today their role in silicon wafer manufacturing processes continues to grow in complexity and scope. As a silicon wafer makes its way down the ...
