The Anapole Moment of Dirac Neutrinos in Left–right Symmetric Model and in Minimal Supersymmetric Model

Abstract

The static parity-violating coupling of Dirac neutrino to an external electromagnetic field is calculated in the SU(2) L × SU(2) R × U(1) left-right model and in the N = 1 broken supergravity model (MSSM).

Contribution of Neutralino and Chargino to Diagonal Form Factor of Majorana Neutrino in the Minimal Supersymmetric Standard Model

“…It is known that in quantum field theory (QFT), the interaction vertex between a single photon and a fermion can be characterized in terms of four electromagnetic (EM) form factors. In the limit of vanishing momentum transfer between the photon and fermion, the form factors encode the static EM properties of the particle [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

Role of neutrino form factors in the energy loss rates of the pair annihilation process

“…The properties of neutrinos have been increasingly researched over the last sixty years. The possible electromagnetic properties of massive neutrinos include a charged radius, an anapole moment, a dipole magnetic, and an electric moment [5][6][7][8][9][10][11][12]. Research on neutrino mass, whether they are Dirac or Majorana particles, oscillations, and form factors and especially on the magnetic moment is of great signi- ficance for the choice of the theory of elementary particles and for clarifying phenomena such a supernova dynamics, stellar evaluation, and the production of sun neutrinos.…”
