symmetry magazine | dimensions of particle physics
WEBJul 25, 2024 · Symmetry is an online magazine that covers particle physics and its connections to other aspects of life and science. It features news, features, interviews, explainers and more about the latest discoveries and developments in the field.
The deconstructed Standard Model equation - symmetry magazine
WEBLearn how the Standard Model of particle physics is written in the Lagrangian form, a fancy way of writing an equation to determine the state of a changing system. See the topics covered in this equation, such as gluons, bosons, matter particles, Higgs field and ghosts.
What is a photon? - symmetry magazine
WEBA photon is the smallest possible packet of electromagnetic energy, also known as a quantum of light. Learn about the history and properties of photons, how they behave as both particles and waves, and how they enable interactions via the electromagnetic force.
Ten things you might not know about antimatter
WEBAntimatter particles annihilate with matter to release huge amounts of energy, but humans have produced only a tiny amount of antimatter. Learn more about antimatter sources, traps, gravity and neutrinos in this article.
Is the neutrino its own antiparticle? | symmetry magazine
WEBSince then, experiments have cropped up across Asia, Europe and North America searching for hints that the neutrino is its own antiparticle. The key to finding this evidence is something called lepton number conservation. Scientists consider it a fundamental law of nature that lepton number is conserved, meaning that the number of leptons and ...
Massless particles can’t be stopped | symmetry magazine
WEBJul 23, 2019 · Massless particles are not matterless, but they are purely energy and travel at the speed of light. Learn how they are created, how they interact with gravity and what types of massless particles exist in the universe.
The Planck scale - symmetry magazine
WEBFeb 22, 2022 · The Planck scale is a set of units based on five constants in nature, such as the speed of light and the gravitational constant. It also marks the minimum length and energy scale where the laws of physics break down, and where quantum gravity and superstrings might emerge.
Meet the kaon - symmetry magazine
WEBNov 10, 2020 · Learn how the kaon, a strange and heavy particle discovered in 1947, led to new insights into quantum physics, quarks and CP symmetry. Explore the history and experiments of kaon research and its implications for the Standard Model.
Four things you might not know about dark matter
WEBLearn about the history, evidence and theories of dark matter, the mysterious substance that makes up most of the universe. Find out how scientists are searching for dark matter particles and what they might look like.
Eight things you might not know about light - symmetry magazine
WEBLearn how photons are particles and waves, how they interact with matter and antimatter, and how they can produce shock waves, Cherenkov radiation, and more. Discover the different types and wavelengths of light, and how scientists use them for …
