Quiver Gauge Theory and Conformality at the TeV Scale
This review describes the conformality approach to extending the standard model of particle phenomenology using an assumption of no conformal anomaly at high energy.

متن کاملAnomaly Cancellation and Conformality in Quiver Gauge Theories
Abelian quiver gauge theories provide nonsupersymmetric candidates for the conformality approach to physics beyond the standard model. Written asN = 0, U(N) gauge theories, however, they have mixed U(1)pU(1) 2 q and U(1)pSU(N) 2 q triangle anomalies. It is shown how to construct explicitly a compensatory term ∆Lcomp which restores gauge invariance of Leff = L+∆Lcomp under U(N). It can lead to a...
متن کاملDark Matter Candidate from Conformality
Abelian quiver gauge theories provide candidates for the conformality approach to physics beyond the standard model which possess novel cancellation mechanisms for quadratic divergences. A Z2 symmetry (R parity) can be imposed and leads naturally to a dark matter candidate which is the Lightest Conformality Particle (LCP), a neutral spin-1/2 state with weak interaction annihilation cross sectio...
متن کاملFermion resonances in quiver theories with a pNGB Higgs
Hierarchical quiver models can be used to build theories of electroweak symmetry breaking and natural models of flavor with a pseudo-Nambu-Goldstone boson (pNGB) Higgs. They are cousins of similar models in extra-dimensional theories in anti-de Sitter backgrounds, and can be obtained from them by coarse deconstruction. We consider the fermion excitations in these models, focusing on the quark s...
متن کاملProbing the Green-Schwarz Mechanism at the Large Hadron Collider
We investigate the phenomenology of new abelian gauge bosons, which we denote as X bosons, that suffer a mixed anomaly with the Standard Model, but are made selfconsistent by the Green-Schwarz mechanism. A distinguishing aspect of the resulting effective theory is the decay of X bosons into Standard Model gauge bosons, X → ZZ,WW, γZ. We compute the production cross-section of the X boson from v...
