The standard model à la Connes-Lott

The Gravitational Sector in the Connes - Lott Formulation of the Standard Model

We study the Riemannian aspect and the Hilbert-Einstein gravitational action of the non-commutative geometry underlying the Connes-Lott construction of the action functional of the standard model. This geometry involves a two-sheeted, Euclidian space-time. We show that if we require the space of forms to be locally isotropic and the Higgs scalar to be dynamical, then the Riemannian metrics on t...

Natural extensions of the Connes–Lott Model and comparison with the Marseille–Mainz Model

An extension of the Connes–Lott model is proposed. It is also within the framework of the A.Connes construction based on a generalized Dirac–Yukawa operator and the K–cycle (H,D), with H a fermionic Hilbert space. The basic algebra A which may be considered as representing the non–commutative extension, plays a less important role in our approach. This allows a new class of natural extensions. ...

Notes on Connes ’ Construction of the Standard Model

The mathematical apparatus of non commutative geometry and operator algebras which Connes has brought to bear to construct a rational scheme for the internal symmetries of the standard model is presented from the physicist’s point of view. Gauge symmetry, anomaly freedom, conservation of electric charge, parity violation and charge conjugation all play a vital role. When put together with a rel...

Contribution à l'étude de la maladie athéromateuse

Médecine à la Molière.

Of Moliere's thirty six plays, seven deal, to a greater or lesser extent, with medicine; the medicine as practiced in Paris during the reign of Louis XIV. In these days, Moliere satirises the recalcitrant conservatism of the Paris medical faculty. It is, however, an informed satirisation. This paper explores Moliere's motives and attempts to place Moliere's medical plays against a broad canvas ...
