Balancing multiple charge particle excesses with baryon asymmetry

Abstract

Stable multiple charged particles can possess electroweak charges, as per the walking technicolor models. An asymmetry of these particles is balanced by sphaleron transitions which among other things can provide an excess of baryons and/or leptons. A possibility to generate sufficient amount of particles with the charge [Formula: see text] to explain the observed dark matter density by dark atoms (which are bound states of multiple charged techniparticles with [Formula: see text] helium nuclei) is considered in the framework of thermodynamic approach.
