"Connes' Approach to the Standard Model of Particle Physics via 
Non-Commutative Geometry"

Thursday 27 Nov. 16:00, SISSA room 136

Connes' notion of non-commutative geometry (NCG) generalizes Riemannian 
geometry and yields a striking reinterepretation of the standard model 
of particle physics, coupled to Einstein gravity.  In my talk I suggest 
a simple reformulation of Connes' approach which resolves a 
long-standing problem plaguing the NCG construction of the standard 
model, by precisely eliminating from the action the collection of 7 
unwanted terms that previously had to be removed by an extra, 
non-geometric, assumption. I will also show how this same reformulation 
yields a new perspective on the symmetries of a given NCG, which offers 
a new solution to the discrepancy between the observed Higgs mass and 
the NCG prediction.
