Spectral noncommutative geometry standard model and all that

A Devastato, M Kurkov, F Lizzi - International Journal of Modern …, 2019 - World Scientific
We review the approach to the Standard Model of particle interactions based on spectral
noncommutative geometry. The paper is (nearly) self-contained and presents both the …

Grand symmetry, spectral action and the Higgs mass

A Devastato, F Lizzi, P Martinetti - Journal of High Energy Physics, 2014 - Springer
A bstract In the context of the spectral action and the noncommutative geometry approach to
the standard model, we build a model based on a larger symmetry. With this grand symmetry …

[HTML][HTML] High energy bosons do not propagate

MA Kurkov, F Lizzi, D Vassilevich - Physics Letters B, 2014 - Elsevier
We discuss the propagation of bosons (scalars, gauge fields and gravitons) at high energy
in the context of the spectral action. Using heat kernel techniques, we find that in the high …

Higgs phenomenology in the minimal dilaton model after Run I of the LHC

J Cao, Y He, P Wu, M Zhang, J Zhu - Journal of High Energy Physics, 2014 - Springer
A bstract The Minimal Dilaton Model (MDM) extends the Standard Model (SM) by a singlet
scalar, which can be viewed as a linear realization of general dilaton field. This new scalar …

Spectral action with zeta function regularization

MA Kurkov, F Lizzi, M Sakellariadou… - Physical Review D, 2015 - APS
In this paper we propose a novel definition of the bosonic spectral action using zeta function
regularization, in order to address the issues of renormalizability and spectral dimensions …

Noncommutative geometry and particle physics

F Lizzi - arxiv preprint arxiv:1805.00411, 2018 - arxiv.org
We review the noncommutative approach to the standard model. We start with the
introduction if the mathematical concepts necessary for the definition of noncommutative …

Spectral regularisation: induced gravity and the onset of inflation

MA Kurkov, M Sakellariadou - Journal of Cosmology and …, 2014 - iopscience.iop.org
Using spectral regularisation, we compute the Weyl anomaly and express the anomaly
generating functional of the quantum effective action through a collective scalar degree of …

Unification of coupling constants, dimension 6 operators and the spectral action

A Devastato, F Lizzi, CV Flores… - International Journal of …, 2015 - World Scientific
We investigate whether inclusion of dimension 6 terms in the Standard Model Lagrangian
may cause the unification of the coupling constants at a scale comprised between 1014 and …

Clifford structures in noncommutative geometry and the extended scalar sector

MA Kurkov, F Lizzi - Physical Review D, 2018 - APS
We consider aspects of the noncommutative approach to the standard model based on the
spectral action principle. We show that as a consequence of the incorporation of the Clifford …

Dimensional deception from noncommutative tori: An alternative to the Horava-Lifshitz model

F Lizzi, A Pinzul - Physical Review D, 2017 - APS
We study the dimensional aspect of the geometry of quantum spaces. Introducing a
physically motivated notion of the scaling dimension, we study in detail the model based on …
