Symmetry (biology) — Bilateral symmetry redirects here. For bilateral symmetry in mathematics, see reflection symmetry. Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some… … Wikipedia
Custodial symmetry — In particle physics with one or more electroweak Higgs doublets in the Higgs sector, the effective action term which generically arises whenever we have new physics beyond the Standard Model at the scale Λ contributes to the Peskin Takeuchi T… … Wikipedia
Chiral symmetry — In quantum field theory, chiral symmetry is a possible symmetry of the Lagrangian under which the left handed and right handed parts of Dirac fields transform independently. The chiral symmetry transformation can be divided into a component that… … Wikipedia
Rotational symmetry — Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted, the … Wikipedia

QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… … Wikipedia
Particle physics and representation theory — There is a natural connection, first discovered by Eugene Wigner, between the properties of particles, the representation theory of Lie groups and Lie algebras, and the symmetries of the universe. According to it, the different states of an… … Wikipedia
