Mathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1218-1235, February 2024.If an initial frame of vectors {ei}$$ \left\{{e}_i\right\} $$ is related to a final frame of vectors {fi}$$ \left\{{f}_i\right\} $$ by, in geometric algebra (GA) terms, a rotor, or in linear algebra terms, an orthogonal transformation, we often want to find this rotor given the initial and final sets of vectors.

European Physical Journal C: Particles and Fields, 2018 We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

The LHC upper bounds for $pp \to \text{diboson}$, $t\bar t$ cross section on fermionic dark matter
, 2017 The ATLAS report in August 2016 provided an upper limit for the $pp\to$ diboson and $t\bar t$ cross sections. We consider a pseudoscalar-mediated fermionic dark matter together with gluon and photon effective operators interacting with the pseudoscalar ...

Pseudoscalar susceptibilities and quark condensates: chiral restoration and lattice screening masses [PDF]
, 2016 A bstractWe derive the formal Ward identities relating pseudoscalar susceptibilities and quark condensates in three-flavor QCD, including consistently the η-η′ sector and the UA(1) anomaly.

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 ...

, 1992 Gluon fusion into a very heavy neutrino pair by Higgs exchange is shown to lead to substantial production cross sections at $pp$ supercolliders even without any extra generation of quarks.

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.

Exploring solutions to the muon g-2 anomaly in a 3-3-1 model under flavor constraints
European Physical Journal C: Particles and FieldsThe magnetic moment of the muon can receive significant two-loop contributions from a light pseudoscalar. Notably, the spectrum of scalars of 3-3-1 models includes one pseudoscalar.
