51Yukawa interaction — In particle physics, Yukawa s interaction, named after Hideki Yukawa, is an interaction between a scalar field phi and a Dirac field Psi of the type:V approx garPsi phi Psi (scalar) or g ar Psi gamma^5 phi Psi (pseudoscalar).The Yukawa… …
52Spin representation — In mathematics, the spin representations are particular projective representations of the orthogonal or special orthogonal groups in arbitrary dimension and signature (i.e., including indefinite orthogonal groups). More precisely, they are… …
53An Exceptionally Simple Theory of Everything — is a preprint proposing a basis for a unified field theory, named E8 Theory , which attempts to describe all known fundamental interactions in physics, and to stand as a possible theory of everything. The preprint was posted to the physics arXiv… …
54Top quark condensate — In particle physics, the top quark condensate theory is an alternative to the Standard Model in which a fundamental scalar Higgs field is replaced by a composite field composed of the top quark and its antiquark. The top quark is chosen because… …

57Mirror symmetry (string theory) — In physics and mathematics, mirror symmetry is a relation that can exist between two Calabi Yau manifolds. It happens, usually for two such six dimensional manifolds, that the shapes may look very different geometrically, but nevertheless they… …
58Moduli (physics) — In quantum field theory, the term moduli (or more properly moduli fields) is sometimes used to refer to scalar fields whose potential energy function has continuous families of global minima. Such potential functions frequently occur in… …
59Gauge covariant derivative — The gauge covariant derivative (pronEng|ˌgeɪdʒ koʊˌvɛəriənt dɪˈrɪvətɪv) is like a generalization of the covariant derivative used in general relativity. If a theory has gauge transformations, it means that some physical properties of certain… …
