Non-commutative geometry deals with spaces where the uncertainty principle of quantum mechanics thwarts even one's ability to simultaneously measure two position co-ordinates. It finds applications in models where geometry is emergent including the matrix model approach to string theory.

What is the most natural new physics one can expect at the TeV scale: new (supersymmetric)pa...

Notice : This is another tentative answer to address (better than in my former one) the naturalness problem raised by the present stalemate for traditional perturbatively renormalisable Susy-Yang-Mill …

115 GeV, 170 GeV, and the non-commutative standard model

The question about the 170 GeV prediction is obsolete now. But the issue: to drive the Higgs mass to the lower bound, rather than to the upper bound, in an altered version of the noncommutativ …

Is the 125 GeV Higgs boson some kind of a "almost-commutative graviton" at the electroweak s...

Let's focus first on the almost-commutative aspect. One could argue that a possibly better formulation for the 126 GeV Higgs scalar could be almost-commutative gauge boson to underline the fact that i …

Implication of the Jacobian map for the structure of the Euclidean space-time

The Heisenberg-like commutation relation $$ \langle Y[D,Y]^{2m} \rangle= \gamma $$ (with $\gamma $ the chirality operator) appeared first in a preprint then a PRL article. It was devised by A. Chamse …

The question is hard to answer not because of its colloquial character but because it tries to establish a comparison bewteen two predictions at the TeV scale sustained by two very different theoreti …
