Regular spinors and fermionic fields
(2021-06-28)
Bearing in mind the Lounesto spinor classification, we connect the expansion coefficients of well behaved fermionic quantum field, i.e., a local field within a full Lorentz covariant theory, with and only with a given ...
The Heisenberg spinor field classification and its interplay with the Lounesto’s classification
(Springer, 2019-03)
Dirac linear spinor fields were obtained from non-linear Heisenberg spinors, in the literature. Here we extend that idea by considering not only Dirac spinor fields but spinor fields in any of the Lounesto’s classes. When ...
Where are ELKO spinor fields in Lounesto spinor field classification?

The quadratic spinor Lagrangian, axial torsion current and generalizations
(World Scientific Publ Co Pte Ltd, 2007-10-01)
We show that the Einstein-Hilbert, the Einstein-Palatini, and the Holst actions can be derived from the Quadratic Spinor Lagrangian (QSL), when the three classes of Dirac spinor fields, under Lounesto spinor field ...

ELKO SPINOR FIELDS: LAGRANGIANS FOR GRAVITY DERIVED FROM SUPERGRAVITY
(World Scientific Publ Co Pte Ltd, 2009-05-01)
Dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields) belong - together with Majorana spinor fields - to a wider class of spinor fields, the so-called flagpole spinor fields, corresponding to ...

Elko spinor fields: Lagrangians for gravity derived from supergravity
(2009-06-17)

A Note on T-dualities in the Pure Spinor Heterotic String
(2013-10-22)
In this note we study the preservation of the classical pure spinor BRST constraints under super T-duality transformations. We also determine the invariance of the one-loop conformal invariance and of the local gauge and ...
