interaction symmetry group
1Symmetry in physics — refers to features of a physical system that exhibit the property of symmetry that is, under certain transformations, aspects of these systems are unchanged , according to a particular observation. A symmetry of a physical system is a physical or …
2Group selection — In evolutionary biology, group selection refers to the idea that alleles can become fixed or spread in a population because of the benefits they bestow on groups, regardless of the alleles effect on the fitness of individuals within that group.… …
3Spontaneous symmetry breaking — Quantum field theory (Feynman diagram) …
4Event symmetry — The term Event symmetry describes invariance principles that have been used in some discrete approaches to quantum gravity where the diffeomorphism invariance of general relativity can be extended to a covariance under any permutation of… …
5Strong interaction — This article is about the phenomenon in particle physics. For the concept in ecology, see Food chain. For the interaction that binds together the particles in atomic nuclei, see Nuclear force. Standard model of particle physics …
6Special unitary group — In mathematics, the special unitary group of degree n , denoted SU( n ), is the group of n times; n unitary matrices with determinant 1. The group operation is that of matrix multiplication. The special unitary group is a subgroup of the unitary… …
7Weak interaction — Standard model of particle physics …
8Electroweak interaction — In particle physics, the electroweak interaction is the unified description of two of the four fundamental interactions of nature: electromagnetism and the weak interaction. Although these two forces appear very different at everyday low energies …
9Renormalization group — In theoretical physics, the renormalization group (RG) refers to a mathematical apparatus that allows systematic investigation of the changes of a physical system as viewed at different distance scales. In particle physics, it reflects the… …
10Quartic interaction — In quantum field theory, a quartic interaction is a theory about a scalar field phi; which contains an interaction term phi^4, and is considered by many teachers and students to be the simplest example of interacting fields. This theory consists… …
