We provide the first details on the unexpected theoretical discovery of a spin-one-half matter field with mass dimension one. It is based upon a complete set of dual-helicity eigenspinors of the charge conjugation operator. Due to its unusual properties with respect to charge conjugation and parity, it belongs to a non-standard Wigner class. Consequently, the theory exhibits non-locality with . We briefly discuss its relevance to the cosmological ‘horizon problem’. Because the introduced… 
Dark matter : A spin one-half fermion field with mass dimension one?
We report an unexpected theoretical discovery of a spin one-half matter field with mass dimension one. It is based on a complete set of eigenspinors of the charge conjugation operator. Because of its
On a local mass dimension one Fermi field of spin one-half and the theoretical crevice that allows it
Since the 1928 seminal work of Dirac, and its subsequent development by Weinberg, a view is held that there is a unique Fermi field of spin one-half. It is endowed with mass dimension three-half.
The Theory of Local Mass Dimension One Fermions of Spin One Half
About a decade ago the present author in collaboration with Daniel Grumiller presented an ‘unexpected theoretical discovery’ of spin one-half fermions with mass dimension one (Ahluwalia-Khalilova and
Symmetries and unitary interactions of mass dimension one fermionic dark matter
The fermionic fields constructed from Elko have several unexpected properties. They satisfy the Klein-Gordon but not the Dirac equation and are of mass dimension one instead of three-half. Starting
Mass-dimension-one fermions and their gravitational interaction
We investigate in detail the interaction between the spin-(1/2) field endowed with mass dimension one and the graviton. We obtain an interaction vertex that combines the characteristics of
A tutorial approach on mass dimension one fermions phenomenological analysis
The mass dimension one spinor is a candidate to explain the dark matter content in our universe. This field is an eingenspinor of charge conjugation operator and has a peculiar mass dimension, which
Mass Dimension One Fermions
In 2005, Dharam Ahluwalia and Daniel Grumiller reported an unexpected theoretical discovery of mass dimension one fermions. These are an entirely new class of spin one half particles, and because of
An unified cosmological evolution driven by a mass dimension one fermionic field
An unified cosmological model for an Universe filled with a mass dimension one (MDO) fermionic field plus the standard matter fields is considered. After a primordial quantum fluctuation the field
Self-interacting mass-dimension one fields for any spin
According to Ahluwalia and Grumiller, massive spin-half fields of mass-dimension one can be constructed using the eigenspinors of the charge-conjugation operator (Elko) as expansion coefficients. In
A story of phases, duals, and adjoints for a local Lorentz covariant theory of mass dimension one fermions
We introduce a fermionic spin one-half quantum field with eigenspinors of the charge conjugation operator as its expansion coefficients. For the eigenspinors we make a very specific choice of the

THEORY OF NEUTRAL PARTICLES: MCLENNAN-CASE CONSTRUCT FOR NEUTRINO, ITS GENERALIZATION, AND A NEW WAVE EQUATION
Continuing our recent argument where we constructed a FNBWW type spin-1 boson having opposite relative intrinsic parity to that of the associated antiparticle, we now study eigenstates of the charge
Extended set of Majorana spinors, a new dispersion relation, and a preferred frame
We aspire to fufill Majorana's original goal of bringing full symmetry between the charged and fundamentally neutral particles. We present a description of fundamentally neutral particles without any

We unearth spacetime structure of massive vector bosons, gravitinos, and gravitons. While the curvatures associated with these particles carry a definite spin, the underlying potentials cannot be,
Nonuniversal soft supersymmetry breaking and dark matter
An analysis is given of the effects of nonuniversal soft supersymmetry-breaking masses in the Higgs sector and in the third generation squark sector, and it is shown that they are highly coupled.
The Stueckelberg Field
In 1938, Stueckelberg introduced a scalar field which makes an Abelian gauge theory massive but preserves gauge invariance. The Stueckelberg mechanism is the introduction of new fields to reveal a

Assuming that quantum Einstein gravity (QEG) is the correct theory of gravity on all length scales, we use analytical results from nonperturbative renormalization group (RG) equations as well as
Integral and Light Dark Matter
The nature of Dark Matter remains one of the outstanding questions of modern astrophysics. The success of the Cold Dark Matter cosmological model argues strongly in favor of a major component of the
Evidence for majorana neutrinos : Dawn of a new ear in spacetime structure
We show that Majorana particles belong to the Wigner class of fermions in which the charge conjugation and the parity operators commute, rather than anticommute. Rigorously speaking, Majorana spinors
