In particle physics, the Georgi–Glashow model is a particular Grand Unified Theory (GUT) proposed by Howard Georgi and Sheldon Glashow in 1974. In this model, the Standard Model gauge groups SU(3) × SU(2) × U(1) are combined into a single simple gauge group SU(5). The unified group SU(5) is then thought to be … See more SU(5) acts on $${\displaystyle \mathbb {C} ^{5}}$$ and hence on its exterior algebra $${\displaystyle \wedge \mathbb {C} ^{5}}$$. Choosing a $${\displaystyle \mathbb {C} ^{2}\oplus \mathbb {C} ^{3}}$$ splitting restricts … See more SU(5) breaking occurs when a scalar field (Which we will denote as $${\displaystyle \mathbf {24} _{H}}$$), analogous to the Higgs field and transforming in the adjoint of SU(5), acquires a vacuum expectation value proportional to the weak hypercharge See more Proton Decay in SU(5) Unification of the Standard Model via an SU(5) group has significant phenomenological implications. Most notable of these is proton decay which is present in SU(5) with and without supersymmetry. … See more Owing to its relatively simple gauge group $${\displaystyle SU(5)}$$ , GUTs can be written in terms of vectors and matrices which allows for an intuitive understanding of the Georgi–Glashow model. The fermion sector is then composed of an anti fundamental See more The minimal supersymmetric SU(5) model assigns a $${\displaystyle \mathbb {Z} _{2}}$$ matter parity to the chiral superfields with the matter fields having odd parity and the Higgs having even parity to protect the electroweak Higgs from quadratic … See more WebAs an illustration, we implemented the Georgi-Glashow SU(5) model. The model predicts the existence of a dark (1 , 24 , 0) + (5 , 5* , −y′) + (5* , 5 , y′) sector and an anomalous U(1) Z . Keywords.

WebFeb 15, 2014 · The Georgi–Glashow model is a natural testing ground for this mechanism which has been surprising us by its richness and wide applicability. In this work, we shed light on two new aspects of this model in 2+1 D. First, we develop a many-body description of the effective degrees of freedom. Namely, we consider a non-relativistic gas of W ... WebAug 3, 2015 · Consider the Georgi-Glashow model, an gauge theory with a real scalar in the adjoint (thus a 3-vector in the colour space) .
