Since a Majorana neutrino is its own antiparticle under $\mathrm{CPT}$, rather than $C$, an analysis of the $\mathrm{CPT}$ and $\mathrm{CP}$ characteristics of a Majorana particle is performed. The $\mathrm{CPT}$ transformation properties of a Majorana particle of arbitrary spin are obtained in a very simple way. Implications of these properties for the electromagnetic matrix elements of Majorana particles of spin \textonehalf{} are derived. Finally, the question of when different Majorana… 

Parity and CP operations for Majorana neutrinos

The parity transformation law of the fermion field $\psi(x)$ is usually defined by the "$\gamma^{0}$-parity" $\psi^{p}(t,-\vec{x}) = \gamma^{0}\psi(t,-\vec{x})$ with eigenvalues $\pm 1$, while the

Operatorial characterization of Majorana neutrinos

The Majorana neutrino $$\psi _{M}(x)$$ ψ M ( x ) when constructed as a superposition of chiral fermions such as $$\nu _{L} + C\overline{\nu _{L}}^{T}$$ ν L + C ν L ¯ T is characterized by $$

Phenomenology of neutron-antineutron conversion

We consider the possibility of neutron-antineutron ($n-\bar n$) conversion, in which the change of a neutron into an antineutron is mediated by an external source, as can occur in a scattering

Stellar energy loss rates beyond the standard model

It is known that the dipole moments of the neutrino lead to important astrophysical and cosmological effects. In this regard, within the context of a $$U(1)_\mathrm{B-L}$$ U ( 1 ) B - L model, we

Studies on the anomalous magnetic and electric dipole moments of the tau-neutrino in pp collisions at the LHC

Abstract.Using the effective Lagrangians formalism, we study the radiative process $ pp\rightarrow (\gamma, Z) \rightarrow \nu_{\tau} \bar{\nu}_{\tau} \gamma +X$pp→(γ,Z)→ντν¯τγ+X in pp collisions at

Neutralino pair production and three body decays at e+ e- linear colliders as probes of CP violation in the neutralino system

In the CP-invariant supersymmetric theories, the steep S-wave (slow P-wave) rise of the cross section for any non-diagonal neutralino pair production in $e^+ e^-$ annihilation, $e^+e^- \to

It is shown that under {ital CPT} invariance all the multipoles of the mass distribution are the same for a particle and its antiparticle and in a quantum theory of gravity the coupling of a particle to the graviton is in general different from that of its antiparticles.

Interaction of Dirac and Majorana neutrinos with weak gravitational fields

In this paper the interaction of high energy neutrinos with weak gravitational fields is briefly explored. The form of the graviton-neutrino vertex is motivated from Lorentz and gauge invariance and

Model-independent sensibility studies for the anomalous dipole moments of theντat the CLIC basede+e−andγe−colliders

To improve the theoretical prediction of the anomalous dipole moments of the $\tau$-neutrino, we have carried out a study through the process $\gamma e^- \to \tau \bar\nu_\tau \nu_e$, which
