Why the Standard Model
Ali H. Chamseddine, Alain Connes
The Standard Model is based on the gauge invariance principle with gauge group U(1)xSU(2)xSU(3) and suitable representations for fermions and bosons, which are begging for a concep…
Conceptual Explanation for the Algebra in the Noncommutative Approach to the Standard Model
Ali H. Chamseddine, Alain Connes
The purpose of this letter is to remove the arbitrariness of the ad hoc choice of the algebra and its representation in the noncommutative approach to the Standard Model, which was…
Quantum Gravity Boundary Terms from Spectral Action of Noncommutative Space
Ali H. Chamseddine, Alain Connes
We study the boundary terms of the spectral action of the noncommutative space, defined by the spectral triple dictated by the physical spectrum of the standard model, unifying gra…
Supergravity vacua and lorentzian Lie groups
Ali Chamseddine, José Figueroa-O'Farrill, Wafic Sabra
We classify maximally supersymmetric backgrounds (vacua) of chiral (1,0) and (2,0) supergravities in six dimensions and, by reduction, also those of the minimal N=2 supergravity in…
Chiral Anomalies in the Spectral Action
Ali H. Chamseddine
The definition of the spectral action involves the trace operator over states in the physical Hilbert space. We show that in the presence of chiral fermions there are consistency c…
Particle Physics Models, Grand Unification, and Gravity in Non-Commutative Geometry
A. H. Chamseddine, J. Fröhlich
We review the construction of particle physics models in the framework of non-commutative geometry. We first give simple examples, and then progress to outline the Connes-Lott cons…
