The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.

Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics. Developed in the early 1970s, it has successfully explained almost all experimental results and precisely predicted a …

The Standard Model of Particle Physics is scientists’ current best theory to describe the most basic building blocks of the universe. It explains how particles called quarks (which make up protons and neutrons) and leptons (which include electrons) make up all known matter.

The standard model of particle physics is a mathematical model that describes electromagnetism, the strong and weak nuclear forces, and the Higgs mechanism.

We describe the Standard Model in detail in terms of electromagnetic, weak nuclear, and strong forces. At the end of this section, we review unification theories in particle physics. The Standard Model of particle interactions contains two ideas: electroweak theory and quantum chromodynamics (QCD) (the force acting between color charges).

2024年12月20日 · Standard model, the combination of two theories of particle physics into a single framework to describe all interactions of subatomic particles, except those due to gravity. The two components of the standard model are electroweak theory, which describes interactions via the electromagnetic and

The Standard Model (SM) of particle physics is a theoretical framework that describes the fundamental particles and their interactions, excluding gravity. It summarizes our current understanding of quantum mechanics and field theory, combining the electroweak interaction and quantum chromodynamics (QCD) into a coherent model.

2022年9月19日 · Physicists began developing the Standard Model in the 1950's, following a series of groundbreaking theoretical and experimental developments. On the theory side, physicists had just extended...

2024年5月28日 · The Standard Model of particle physics is an incredibly successful scientific theory that provides a comprehensive framework for understanding the fundamental particles and forces of the universe. It is the culmination of decades of research and experimentation in the field of quantum mechanics and particle physics.

2024年12月19日 · The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known subatomic particles. It was developed throughout the latter half of the 20th century, as a collaborative effort of scientists around the world.
