Noncommutative gauge theories on D-branes in non-geometric backgrounds
Journal of High Energy Physics, 2019 We investigate the noncommutative gauge theories arising on the worldvolumes of D-branes in non-geometric backgrounds obtained by T-duality from twisted tori.

Top Quark Pair-Production in Noncommutative Standard Model
Advances in High Energy Physics, 2020 The differential cross-section of the top quark pair production via the quark-antiquark annihilation subprocess in hadron collision is calculated within the noncommutative standard model. A pure NC analytical expression for the forward-backward asymmetry

Zitterbewegung in noncommutative geometry [PDF]
International Journal of Modern Physics A, 2019 We have considered the effects of space and momentum noncommutativity separately on the zitterbewegung (ZBW) phenomenon. In the space noncommutativity scenario, it has been expressed that, due to the conservation of momentum, the Fourier decomposition of the expectation value of position does not change.

Time discretization from noncommutativity
Physics Letters B, 2021 We show that a particular noncommutative geometry, sometimes called angular or ρ-Minkowski, requires that the spectrum of time be discrete. In this noncommutative space the time variable is not commuting with the angular variable in cylindrical ...

Possible Effects of Noncommutative Geometry on Weak CP Violation and Unitarity Triangles [PDF]
, 2002 Possible effects of noncommutative geometry on weak CP violation and unitarity triangles are discussed by taking account of a simple version of the momentum-dependent quark mixing matrix in the noncommutative standard model.

Geometry of Quantum Projective Spaces [PDF]
, 2012 In recent years, several quantizations of real manifolds have been studied, in particular from the point of view of Connes' noncommutative geometry. Less is known for complex noncommutative spaces.

The Geometry of Noncommutative Spacetimes
Universe, 2017 We review the concept of ‘noncommutative spacetime’ approached from an operational stand-point and explain how to endow it with suitable geometrical structures. The latter involves i.a.

Type-II two-Higgs-doublet model in noncommutative geometry
Nuclear Physics B, 2022 In noncommutative geometry (NCG) the spectral action principle predicts the standard model (SM) particle masses by constraining the scalar and Yukawa couplings at some heavy scale, but gives an inconsistent value for the Higgs mass.

INFLATIONARY COSMOLOGY FROM NONCOMMUTATIVE GEOMETRY [PDF]
International Journal of Modern Physics A, 1996 In the framework of the Connes-Lott model based on noncommutative geometry, the basic features of a gauge theory in the presence of gravity are reviewed, in order to show the possible physical relevance of this scheme for inflationary cosmology. These models naturally contain at least two scalar fields, interacting with each other whenever more than ...

Higher-Dimensional Regular Reissner–Nordström Black Holes Associated with Linear Electrodynamics
Universe, 2022 Following the interpretation of matter source that the energy-momentum tensor of anisotropic fluid can be dealt with effectively as the energy-momentum tensor of perfect fluid plus linear (Maxwell) electromagnetic field, we obtain the regular higher ...
