B-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry

Journal of High Energy Physics, 2018
Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG).

Noncommutative Induced Gauge Theories on Moyal Spaces

, 2007
Noncommutative field theories on Moyal spaces can be conveniently handled within a framework of noncommutative geometry. Several renormalisable matter field theories that are now identified are briefly reviewed.

Metric perturbations in noncommutative gravity

Journal of High Energy Physics
We use the framework of Hopf algebra and noncommutative differential geometry to build a noncommutative (NC) theory of gravity in a bottom-up approach.

From Noncommutative Sphere to Nonrelativistic Spin

Symmetry, Integrability and Geometry: Methods and Applications, 2010
Reparametrization invariant dynamics on a sphere, being parameterized by angular momentum coordinates, represents an example of noncommutative theory.

Modular curvature for toric noncommutative manifolds

, 2015
A general question behind this paper is to explore a good notion for intrinsic curvature in the framework of noncommutative geometry started by Alain Connes in the 80s.

WKB Approximation in Noncommutative Gravity

Symmetry, Integrability and Geometry: Methods and Applications, 2007
We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency ...

Time-dependent Aharonov–Bohm effect on the noncommutative space

Physics Letters B, 2016
We study the time-dependent Aharonov–Bohm effect on the noncommutative space. Because there is no net Aharonov–Bohm phase shift in the time-dependent case on the commutative space, therefore, a tiny deviation from zero indicates new physics. Based on the

Index Theorem in Finite Noncommutative Geometry

, 2007
Index theorem is formulated in noncommutative geometry with finite degrees of freedom by using Ginsparg-Wilson relation. It is extended to the case where the gauge symmetry is spontaneously broken.
