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 …

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 …

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

Dec 2, 2025 · 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 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 …

Mar 26, 2025 · In this section, we introduce the Standard Model, which is the best current model of particle interactions. We describe the Standard Model in detail in terms of electromagnetic, …

May 23, 2025 · At the core of the Standard Model lie two main classes of particles: quarks and leptons. These are the “matter particles,” the ingredients that combine to form the world we …

These lectures provide a basic introduction to the Standard Model (SM) of particle physics.

To describe the fundamental interactions of particles we need a theory of Relativistic Quantum Mechanics Schr¨odinger Equation for a free particle Eˆψ= pˆ2. 2m ψ with energy and …

To use quantum field theory to predict the behavior of fundamental particles, we need to understand the interactions (or forces) between the particles. We need a mathematical model …
