Sep 22, 2022 · The Standard Model of physics is the theory of particles, fields and the fundamental forces that govern them. It tells us about how families of elementary particles group together to form larger ...
Jul 18, 2007 · The standard model of particle physics is more than a model. It is a detailed theory that encompasses nearly all that is known about the subatomic particles and forces in a concise set of ...
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. It also explains how force carrying particles, which belong to a ...
In the hope of avoiding negative energy solutions, Dirac sought a linear relativistic wave equation: ∂t i ∂ψ =. (−i⃗α. ∇ ⃗ + βm)ψ. ⃗α and β. are appropriate 4x4 matrices. ψ is a column vector “spinor” of four wavefunctions. Two of the wavefunctions describe the states of a fermion, but the other two still have negative ...
Nov 10, 2001 · Model Theory. First published Sat Nov 10, 2001; substantive revision Fri Oct 16, 2020. Model theory began with the study of formal languages and their interpretations, and of the kinds of classification that a particular formal language can make. Mainstream model theory is now a sophisticated branch of mathematics (see the entry on first-order ...

The standard model is a quantum field theory, that is, it explains forces in terms of exchanges of quanta of fields, such as the photon and the gluon. But general relativity considers gravity to be a result not of particle exchanges, but of the curvature of space-time.
