Physics predicts that matter and antimatter must be created in almost equal quantities, and that this would have been the case during the Big Bang. What's more, it is predicted that the laws of physics should be the same if a particle is interchanged with its antiparticle – a relationship...
The antiparticle of a matter neutral particle belongs to the same class of matter neutral particles. A truly neutral particle is a particle identical with its antiparticle; it belongs necessarily to the class of matter neutral particles. All known interactions of the Standard Model conserve baryon...
Symmetry in physics explores particle behavior under spatial, temporal, and quantum number reversals, involving both discrete and continuous changes. It underpins the consistency of natural laws and experiment reproducibility, heavily influencing modern physics theories like supersymmetry and potentially unveilin...
What is the relative mass of an alpha particle? What is the antiparticle of an electron? What is a boson particle? What is a lepton? What is the relative mass of an electron? What is a mass defect in nuclear physics? What is nuclear decay?
Scientists say they can explain dark matter by positing a particle that links to a fifth dimension.While the “warped extra dimension” (WED) is a trademark of a popular physics model first introduced in 1999, this research, published in The European Physical Journal C, is the first to ...
If the neutrino — a tiny, ghostly particle that barely interacts with other matter — actually is its own antiparticle, that might be the key to solving this problem. In this theory, at the start of time, a small fraction of neutrinos would have been able to transition from antimatter to...
Yes, this breakthrough in quantum physics is as heady as it sounds. A charm meson particle, after all, can exist in a state where it is both itself and its evil twin (the antiparticle version) at once. This state is known as "quantum superposition," and it's at the heart of the ...
Pi shows up everywhere, from particle physics to sacred geometry. But why? In honor of Pi Day—March 14—let's examine the history of this fascinating number. History of Pi As a concept, pi has been in use since at least the time of the Babylonians and ancient Egypt: both approximated...
It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other particle (for instance, the particles of "Earth" and the particles ...
Muons are unique particles in the standard model of particle physics and have wide-ranging applications. A high-performance muon source is an important experimental platform for comprehensive scientific research internationally. Wang Sheng explained that muons and neutrons are ideal probes for detecting th...
