Influence of the nuclear electric field on processes of annihilation of positrons emitted at β+-decay [PDF]

Ядерна фізика та енергетика, 2014
The process of atomic shell ionization during annihilation of positron, emitted at β+-decay, with K-electron of daughter's atom is considered. The role of nuclear Coulomb field at calculation of the probability of this process is investigated.

Light dark matter through assisted annihilation [PDF]

, 2016
In this paper we investigate light dark matter scenarios where annihilation to Standard Model particles at tree-level is kinematically forbidden. In such cases annihilation can be aided by massive Standard Model-like species, called assisters, in the ...
