TL;DR
This paper explores how cosmic ray signals from PAMELA and ATIC can be explained within a Standard Model extension involving type II seesaw and a stable scalar dark matter, addressing the boost factor issue.
Contribution
It introduces a model combining type II seesaw with a stable scalar dark matter to explain cosmic ray signals and the boost factor within the Standard Model framework.
Findings
Cosmic ray signals can be explained with the extended SM model.
The model provides a particle physics basis for the boost factor.
Stable scalar boson acts as dark matter candidate.
Abstract
We discuss how the cosmic ray signals reported by the PAMELA and ATIC/PPB-BETS experiments may be understood in a Standard Model (SM) framework supplemented by type II seesaw and a stable SM singlet scalar boson as dark matter. A particle physics explanation of the 'boost' factor can be provided by including an additional SM singlet scalar field.
