Electromagnetic properties of neutrinos from scattering on bound electrons in atom

Electromagnetic radiation from bound electrons

Electromagnetic scattering from relativistic bound states.

The quasipotential formalism for elastic scattering from relativistic bound states is formulated based on the instant constraint in the Breit frame. The quasipotential electromagnetic current is derived from Mandelstam's vepoint kernel and obeys a two-body Ward identity. Breit-frame wave functions are obtained directly by solving integral equations with nonzero total threemomentum, thus accompl...

An analysis of electromagnetic scattering from finite-width strips

Majorana neutrinos and their electromagnetic properties

To help develop a picture of Majorana neutrinos, we study their electromagnetic properties. We show' that CPT invariance forbids a Majorana neutrino from having a magnetic or electric dipole moment. Then, by considering the process y~vV, we find the most general expression for the matrix element of the electromagnetic current of a Majorana neutrino. The result is verified in a way which leads u...

Properties of the Schrödinger Theory of Electrons in Electromagnetic Fields

The Schrödinger theory of electrons in an external electromagnetic field can be described from the perspective of the individual electron via the ‘Quantal Newtonian’ laws (or differential virial theorems). These laws are in terms of ‘classical’ fields whose sources are quantal expectations of Hermitian operators taken with respect to the wave function. The laws reveal the following physics: (a)...
