Unraveling the Physical Meaning Behind Elko's Dual structure
Gabriel Brandão de Gracia, Rodolfo José Bueno Rogerio, Luca Fabbri
In this work, we shall analyze the necessity of a proper definition of the dual structure for Elko spinors, and singular spinors in general. We examine in detail why the Dirac dual…
On Wigner Degeneracy in Elko theory: Hermiticity and Dark Matter
G. B. de Gracia, Roldão da Rocha, R. J. Bueno Rogerio +1
In this paper, we provide a set of Hermitian interactions for quantum fields based on Elko, considering the recent achievements concerning the most general form of singular spinors…
A note on hidden classes in spinor classification
R. J. Bueno Rogerio, R. T. Cavalcanti, C. H. Coronado Villalobos +1
The Lounesto classification is a well-established scheme for categorizing spinors based on their physical content, which are determined by their associated bilinear forms. It consi…
Singular spinors as expansion coefficients of local spin-half fermionic and bosonic fields: On the two-fold Wigner degeneracy
R. J. Bueno Rogerio, C. H. Coronado Villalobos
By scrutinizing the singular sector of the Lounesto spinor classification, we investigate the correct definition of the expansion coefficient functions of local fermionic fields wi…
Revisiting Takahashi's inversion theorem in discrete symmetry-based dual frameworks
R. J. Bueno Rogerio, R. T. Cavalcanti, J. M. Hoff da Silva +1
The so-called Takahashi's \emph{Inversion Theorem}, the reconstruction of a given spinor based on its bilinear covariants, are re-examined, considering alternative dual structures.…
Exploiting new classes of mass-dimension one fermions
Rodolfo José Bueno Rogerio, Luca Fabbri
In this paper, we advance in investigating a specific set of eigenvectors of a linearly-independent square root of the identity matrix to obtain a new class of spin-half mass-dimen…
Spinorial discrete symmetries and adjoint structures
J. M. Hoff da Silva, R. J. Bueno Rogerio, N. C. R. Quinquiolo
Extending the investigations about the theory of duals, we analyze duals built up with the aid of discrete symmetry operators. We scrutinize algebraic and physical constraints (enc…
Spinorial structures, discrete symmetries and some consequences
C. H. Coronado Villalobos, R. J. Bueno Rogerio, A. R. Aguirre
In this paper we discuss fundamental aspects related to the helicity and dynamics of the spin- fermions encompassed within the very well-known Lounesto's classification. More…
Non-standard Dirac adjoint spinor: The emergence of a new dual
R. J. Bueno Rogerio, C. H. Coronado Villalobos
In this present communication we provide a new derivation of the Dirac dual structure by employing a different approach from the originally proposed. Following a general and rigoro…
Effective lagrangian for a mass dimension one fermionic field in curved spacetime
R. J. Bueno Rogerio, J. M. Hoff da Silva, M. Dias +1
In this work we use momentum-space techniques to evaluate the propagator for a spin mass dimension one spinor field on a curved Friedmann-Robertson-Walker s…
An alternative approach concerning Elko spinors and the hidden unitarity
L. C. Duarte, R. de C. Lima, R. J. Bueno Rogerio +1
In this theoretical communication we look towards understand the underlying phenomenology concerning the Elko spinors within VSR theory. The program to be accomplished here start w…
On the Spinor Representation
J. M. Hoff da Silva, C. H. Coronado Villalobos, R. J. Bueno Rogerio +1
A systematic study of the spinor representation by means of the fermionic physical space is accomplished and implemented. The spinor representation space is shown to be constrained…
On the bilinear covariants associated to mass dimension one spinors
J. M. Hoff da Silva, C. H. Coronado Villalobos, R. J. Bueno Rogerio +1
In this paper we approach the issue of Clifford algebra basis deformation, allowing for bilinear covariants associated to Elko spinors which satisfy the Fierz-Pauli-Kofink identiti…
The connection between Dirac dynamic and parity symmetry
C. H. Coronado Villalobos, R. J. Bueno Rogerio
Dirac spinors are important objects in the current literature, the algebraic structure presented in the text-books is a general method to write it, however, not unique. The purpose…
The local vicinity of spins sum for certain mass dimension one spinors
R. J. Bueno Rogério, J. M. Hoff da Silva
It is well known that the usual formulation of Elko spinor fields leads to a subtle Lorentz symmetry break encoded in the spin sums. Recently it was proposed a redefinition in the…
