Grand unified theories
Websights, one of us (Lisi) proposed a new unified theory in 2007. The basic idea is to extend Grand Unified Theories and include gravity as part of a consistent geometric framework. In this uni-fied field theory, called E8 theory, all forces and matter are de-scribed as the twisting of a single geometric object.

In particle physics, a Grand Unified Theory (GUT) is a model in which, at high energies, the three gauge interactions of the Standard Model comprising the electromagnetic, weak, and strong forces are merged into a single force. Although this unified force has not been directly observed, many GUT models theorize its … See more Historically, the first true GUT which was based on the simple Lie group SU(5), was proposed by Howard Georgi and Sheldon Glashow in 1974. The Georgi–Glashow model was preceded by the semisimple Lie algebra See more The supposition that the electric charges of electrons and protons seem to cancel each other exactly to extreme precision is essential for the … See more The unification of forces is possible due to the energy scale dependence of force coupling parameters in quantum field theory called renormalization group "running", which allows … See more Several theories have been proposed, but none is currently universally accepted. An even more ambitious theory that includes all fundamental forces, including gravitation, is termed a See more SU(5) SU(5) is the simplest GUT. The smallest simple Lie group which contains the standard model, … See more Since Majorana masses of the right-handed neutrino are forbidden by SO(10) symmetry, SO(10) GUTs predict the Majorana masses … See more A GUT model consists of a gauge group which is a compact Lie group, a connection form for that Lie group, a Yang–Mills action for that connection … See more WebThe Algebra of Grand Unified Theories Grand Unified Theories More precisely, we want: I A homomorphism φ: GSM → G.

WebOct 13, 2024 · The story goes that the electromagnetic and weak forces are unified at a high energy scale, into a single “electroweak force”. The same mathematical symmetry applies, but it’s said to be “spontaneously … WebAbstract. Grand unified theories, in which the strong and electroweak interactions are embedded into an underlying theory with a single gauge coupling constant, are reviewed. A detailed description is given of many of the necessary background topics, including gauge theories, spontaneous symmetry breaking, the standard SU 2 x U 1 electroweak ...
WebOct 13, 2024 · I was talking to a guy the other day about Grand Unified Theories, and I thought I ought to say something about them. The Wikipedia Grand Unified Theory article gives a fair account. It says a … WebGrand unified theories describe the interactions of quarks and leptons within the same theoretical structure. This gives rise to the possibility that quarks can decay to leptons and specifically that the proton can decay. Early attempts at a GUT predicted that the proton’s lifetime must be in the region of 10 32 years.
