Chiral Lagrangian with higher resonances and flavour $ SU(3) $ breaking
, 1993 A chiral Lagrangian with $ SU(3) $ breaking and higher resonances is proposed. In this model, the $ SU(3) $ breaking structure in vector-pseudoscalar sector is realized with the decay constants of pseudoscalar mesons and the masses of vector mesons used ...

Spin 1/2 one‐ and two‐particle systems in physical space without eigen‐algebra or tensor product
Mathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1457-1470, February 2024.Under the spin–position decoupling approximation, a vector with a phase in 3D orientation space endowed with geometric algebra substitutes the vector–matrix spin model built on the Pauli spin operator. The standard quantum operator‐state spin formalism is replaced with vectors transforming by proper and improper rotations in the same 3D space ...

Systematizing the effective theory of self-interacting dark matter
Journal of High Energy Physics, 2020 If dark matter has strong self-interactions, future astrophysical and cosmological observations, together with a clearer understanding of baryonic feedback effects, might be used to extract the velocity dependence of the dark matter scattering rate.

Distinguishing scalar from pseudoscalar Higgs production at the LHC
, 2002 In this letter we examine the production channels for the scalar or pseudoscalar Higgs plus two jets at the CERN Large Hadron Collider (LHC). We identify possible signals for distinguishing between a scalar and a pseudoscalar Higgs boson.Comment: 7 pages,

Mathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1471-1491, February 2024.Different ways of representing the group SU(3)$$ SU(3) $$ within a Geometric Algebra approach are explored. As part of this, we consider characteristic multivectors for SU(3)$$ SU(3) $$ and how these are linked with decomposition of generators into commuting bivectors. The setting for this work is within a 6d Euclidean Clifford Algebra.

The a0(980) in the single Cabibbo-suppressed process Λc → π0ηp
Physics Letters B, 2023 In this work, we have investigated the Cabibbo-suppressed process Λc→π0ηp, by taking into account the intermediate scalar state a0(980), which could be dynamically generated from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary ...

Exploration of Wire Array Metamaterials for the Plasma Axion Haloscope
Annalen der Physik, Volume 536, Issue 1, January 2024.Wire array metamaterials have been proposed as ideal resonators for dark matter searches at the very high masses predicted for the post‐inflation axion, offering the prospect of making resonators simultaneously of very high frequency and very large volume. A detailed exploration of the properties of such wire array metamaterials provides strong support

Sensitivity of Resonant Axion Haloscopes to Quantum Electromagnetodynamics
Annalen der Physik, Volume 536, Issue 1, January 2024.The axion is a well‐motivated particle, which can also explain the existence of dark matter. Furthermore, if magnetic monopoles exist, interactions of electromagnetic fields with axions will be expanded from one parameter to three. In this article, new ways to search for axions are determined and a possible indirect way to determine if magnetically ...
