Quantum fields on noncommutative spacetimes: theory and phenomenology

AP Balachandran, A Ibort, G Marmo… - … Integrability and Geometry …, 2010 - emis.de
In the present work we review the twisted field construction of quantum field theory on
noncommutative spacetimes based on twisted Poincaré invariance. We present the latest …

Muon anomalous magnetic moment in the standard model extension

S Aghababaei, M Haghighat, I Motie - Physical Review D, 2017 - APS
We consider the standard model extension to explore the anomalous magnetic dipole
moment of the muon. In the QED part of the theory for the CP and CPT-even Lorentz …

Hydrogen and muonic hydrogen atomic spectra in non-commutative space-time

M Haghighat, M Khorsandi - The European Physical Journal C, 2015 - Springer
Comparing electronic hydrogen with muonic hydrogen shows that the discrepancy in
measurement of the Lamb shift in the both systems are relatively of order of (m_ μ m_e)^ 4-5 …

Lorentz violation in the Higgs sector and the noncommutative standard model

S Aghababaei, M Haghighat, A Kheirandish - Physical Review D—Particles …, 2013 - APS
The noncommutative standard model apparently violates the Lorentz symmetry. We
compare the Lorentz-violating terms in the Higgs sector of the noncommutative standard …

Location and direction dependent effects in collider physics from noncommutativity

M Haghighat, N Okada, A Stern - … Review D—Particles, Fields, Gravitation, and …, 2010 - APS
We examine the leading order noncommutative corrections to the differential and total cross
sections for e+ e-→ qq¯. After averaging over the Earth's rotation, the results depend on the …

[HTML][HTML] A new limit for the noncommutative space–time parameter

M Moumni, A BenSlama, S Zaim - Journal of Geometry and Physics, 2011 - Elsevier
The spectrum of the hydrogen atom in the framework of noncommutative quantum
mechanics is studied and the related phenomenology is presented. We find that the …

Causality and statistics on the Groenewold–Moyal plane

AP Balachandran, A Joseph, P Padmanabhan - Foundations of Physics, 2010 - Springer
Quantum theories constructed on the noncommutative spacetime called the Groenewold–
Moyal plane exhibit many interesting properties such as Lorentz and CPT noninvariance …

Quantization of Length in Spaces with Position-Dependent Noncommutativity

J Aryampilly, M Balasundaram, A Rashid - arXiv preprint arXiv:2309.12663, 2023 - arxiv.org
We present a novel approach to quantizing the length in noncommutative spaces with
positional-dependent noncommutativity. The method involves constructing ladder operators …

Spectrum of hydrogen atom in space-time non-commutativity

M Moumni, A BenSlama, S Zaim - arXiv preprint arXiv:1003.5732, 2010 - arxiv.org
We study space-time noncommutativity applied to the hydrogen atom and its
phenomenological effects. We find that it modifies the potential part of the Hamiltonian in …
