Solar chameleons: Novel channels

Understand

We revisit the flux of chameleons (light scalar particles which could play a role in the dark energy phenomenon) produced in the interior of the Sun.

• Our novel analysis incorporates various important details and new processes that have previously been overlooked, including the impact of the bulk magnetic field profile, as well as Primakoff production of chameleons in the electric fields of electrons and ions.
• In this paper we consider only the contributions of transverse photons.
• The production of chameleons from longitudinal electromagnetic excitations will be presented in a dedicated follow-up work.
