Simple Relations between Elements of the Three-Dimensional Orthogonal Matrix of the Basic Representation and Euler and RPY’ Angles [PDF]

In this Article transformation angles of the methods of RPY (Roll, Pitch and Yaw) and Euler are found using Spinor method [Milnikov A.A., Prangishvili A.I., Rodonaia I.D.

Carroll fermions

SciPost Physics
Using carefully chosen projections, we consider different Carroll limits of relativistic Dirac fermions in any spacetime dimensions. These limits define Carroll fermions of two types: electric and magnetic.

3+1D Massless Weyl Spinors from Bosonic Scalar-Tensor Duality

Advances in High Energy Physics, 2014
We consider the fermionization of a bosonic-free theory characterized by the 3+1D scalar-tensor duality. This duality can be interpreted as the dimensional reduction, via a planar boundary, of the 4+1D topological BF theory.

Three generations and a trio of trialities

Physics Letters B
We identify the Standard Model's su(3)⊕su(2)⊕u(1) internal symmetries within the triality symmetries tri(C)⊕tri(H)⊕tri(O). From here, the corresponding Standard Model group action is applied to the triality triple (Ψ+,Ψ−,V) for Ψ+,Ψ−,V∈C⊗H⊗O. Together, Ψ+

Massless representation of massive superfields and tree amplitudes with the pure spinor formalism

Journal of High Energy Physics
We construct the unintegrated vertex operator at the first mass level of the open superstring from the OPE of massless vertices. Using BRST cohomology manipulations, the tree amplitude of two massless and one massive state is rewritten in terms of the ...

Wigner multiplets in QFT: from Wigner degeneracy to Elko fields

Journal of High Energy Physics
We establish the theoretical foundation of the Wigner superposition field, a quantum field framework for spin-1/2 fermions that exhibit a Wigner doublet — a discrete quantum number arising from nontrivial representations of the extended Poincaré group ...

Explicit Families of Spinor Representations

We provide a recipe for building explicit representations of the real Clifford algebras once an explicit family is given in dimensions $1$ through $4$. We further give an explicit construction of spin coordinate systems for a given real spinor module and use it to explicitly compute the parallel transport of spinor fields.

Kallen-Lehmann representation for Spinor-Scalar Loops in de Sitter Space-time. Spectral equations

Journal of High Energy Physics
Compact formulas (2.1), (3.14) presented in this paper permit to formulate the Kallen-Lehmann harmonic decompositions of the products of two spinor and of spinor and scalar harmonic functions on AdS and Wightman functions on dS spaces; the correct flat ...
