Constraining Elko Dark Matter at the LHC with Monophoton Events
Alexandre Alves, M. Dias, F. de Campos +2
A mass dimension one fermion, also known as Elko, constitutes a dark matter candidate which might interact with photons at the tree level in a specific fashion. In this work, we in…
A nearly cylindrically symmetric source in the Brans-Dicke gravity as the generator of the rotational curves of the galaxies
S. Mittmann dos Santos, J. M. Hoff da Silva, M. E. X. Guimarães +1
Observation shows that the velocities of stars grow by approximately 2 to 3 orders of magnitude when the distances from the centers of the galaxies are in the range of kpc to…
Opening the Pandora's box of quantum spinor fields
L. Bonora, J. M. Hoff da Silva, R. da Rocha
Lounesto's classification of spinors is a comprehensive and exhaustive algorithm that, based on the bilinears covariants, discloses the possibility of a large variety of spinors, c…
The (restricted) Inomata-McKinley spinor representation and the underlying topology
D. Beghetto, J. M. Hoff da Silva
The so called Inomata-McKinley spinors are a particular solution of the non-linear Heisenberg equation. In fact, free linear massive (or mass-less) Dirac fields are well known to b…
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…
Straight spinning cosmic strings in Brans-Dicke gravity
S. Mittmann dos Santos, J. M. Hoff da Silva, J. L. Cindra
It is presented an exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation. The possibility of the existence of closed timelike curves around these…
